Okay so I tried to play 2 pub games before.
First game we had a drow who sat in fountain after buying 3 salves and 3 clarities. She disconnected. After reconnecting she complained that the shop wouldn't let her buy anything. She disconnected again then reconnected and bought boots on the courier. I picked up the boots from the courier but then they became bound to me but unsellable (?) They were invisible in my inventory to everyone else but if I put them on the ground they were pingable, they also couldn't be denied or anything. Drow disconnected a third time and still was unable to buy any items, we then noticed that when she used a salve it was instantly restored in her inventory. She literally had infinite amounts of salves and clarities. I tried to drop the boots from before but they kept spawning in my inventory after a couple of seconds. The courier also had a boots of speed (also bound to me) stuck in it that was invisible to everyone but me but I could drop them on the ground.
Anyway we won the match because Drow had literally endless salves and would just salve everything non-stop the whole match.
Second game there was a sniper bottom, turns out that if a player disconnects during a match they are taken over by a bot. This was no ordinary bot though, it was invincible. No joke you could not deal any damage to it what-so-ever. It was also immune to any magic/composite/pure damages. Luckily it would stay in the offlane and just attack creep, it wouldn't attack the tower or move it would just pace back and forth killing any creep (or heroes) that got too close. The player never reconnected and the bot stayed there the whole game just being invincible and pacing around.

EDIT: I thought they removed drops? I've played about 12 ranked and 3 pubs since the patch and not a single drop did I see from the end of the game.
