Seems Beaglerush is waiting for some bugfixes to continue his Impossible LP, too. Shame these issues are still around.
Understandable, the bugs are very frustrating on I/I.
For myself the first 2 missions of I/I attempt #5 went smooth. First one was on the gas station map. I hid 2 soldiers behind the van and skirted 2 others around the edge until they got to the roof, luckily no packs aggro'd. Used the ledge peek tactic and found one pack, and with 1 grenade and some bad mind merger positioning got 2, the other one died next turn. As I was re-grouping on the roof the tele-port bug hit, 3 sectoids right in the middle of my ground troops. I was again fortunate with my positioning and was able to shield both from 1 with a big truck and use 2 grenades to ensure the close ones died. With everyone now on the roof I kept using the ledge peek to find the last pack, only 2 sectoids this time, and it was easy enough to flank and kill the merger. 3 promotions- sniper, support, assault.
The first abduction came only a day later, and was another map where I could take advantage of the roof tops- the bakery/butcher shop map. A couple of very tense moments this mission, the first was against the first encounter. There's really no way to get perfect positioning here- the sectoids start right inside the bakery. After overwatching behind the van for 1 turn, I peeked around the corners and found 1 on the corner of the van and 1 on the opposite side- being mind merged from 1 behind the counter. The flanking bug struck this time and I wasted 1 turn from my assault moving him to the corner only still see the 40 cover bonus still there. I spent a while thinking what to do, before settling on this- I run'n'guned my assault to behind the 1 sectoid and used the shotgun on him, lucky it was a 1 shot 1 kill, then I used my peeking sniper and was just able to barely get a grenade on the mind merger, taking 3 health and it's cover, unfortunately I had to run past the other sectoid to get line of sight on him, and I figured he was on overwatch, and I was right. I sent out the rookie and very luckily the sectoid completely missed the easy shot, unfortunately so did the rookie, so I had to use the super-soldier support and pray I didn't miss a 90% shot with 2 soldier lives on the line- he hit.
Whew. I moved on to the roof, and when I got to the back 2 packs aggro'd- 6 total aliens. I moved everyone out of sight and overwatched. 1 sectoid ran to the roof and 2 close overwatches missed and the shotgun hit for 2 damage. I was again in position where I should have had a flanked shot but didn't, so I peeked over the ledge to see where everyone went. One was far away mind merging the sectoid on the roof, 1 was behind a truck mind merging a guy near the bottom of the ladder I couldn't see. I spent about 20 minutes thinking what to do, I really wanted to take all 4 of these guys out before they could get on the roof. Eventually I moved the assault to the edge and lobed a grenade on the far sectoid, destroying his cover, that gave my support a 100% shot and I got those two. I moved the rookie to flank the last merger and he hit the 85% shot but for only 2 damage. My last hope was the sniper and he missed. 2 of the remaining 4 sectoids shot on the sniper, 1 hit for 3 damage, the other missed- lucky. Then my rookie finished of the same mind merger behind the truck. That left 2 and I was able to locate a meger inside the bakery, my support dropped down and used a grenade, and the rookie once again was in the right spot and got a point blank pistol shot. 3 groups down- 1 to go. I moved to the roof of the butchery and pinned down the last group on the side. A couple of turns of missing/hitting high percentage flanked shots and finally the last sectoid ran into my overwatch sniper. 3 more promotions- corp sniper, corp support, and a heavy.
I started research on alien materials, for carapace armour, built 2 sats and a workshop. But now I've run into shitty luck with mission timing. From getting an abduction on day 30, it's now day 20 without another, and I don't have the money for an uplink. I just got a downed UFO mission, which I still don't think will get me enough money to build one. So if I don't get an abduction in the next 5 days I won't have time and I'm going to lose at least 3 countries the first month, and probably 4.
BTW I'm using 3 of the second wave options- New economy, not created equality, and hidden potential. The support is the only good soldier I got out of the starting 4, 70 aim and 50 will as a rookie. The rest are terrible, especially the sniper, as a corporal now he has an aim of 64- 1
below the rookie base. The assault and heavy both have an aim of 58 as squaddies. The rest of the platoon of rookies isn't bad though, about half have aim of 70 and will between 50-55. No super soldiers though, people with aim of 80 as rookies.
