I don't know of any drama, but there was a whole bunch of hatred for him during the RLM stream (in the chat, not this thread) when they showed Gorilla Interrupted. It clearly went beyond hatred for his performance so I assumed there was something I didn't know.
Essentially, from what I gather, Gilchrist spends most of his time working on
remastering The Thief and the Cobbler and doing fan-art commissions of My Little Pony characters to fund his work. He streams his process on a usual basis, and some guys on 4chan decided to hit up his stream to ask him about his RLM days.
He gets surprised by the sudden increase in viewers and goes off about how he is not friends with the guys, and he details this story about how he really hated Jay, and thought Mike was a racist scumbag (Never really explaining why). He also claimed that Jay and Mike had a big fight over both of them liking the same girl which led to them "breaking up" for a long time before making amends and rebuilding RLM. He also criticized Jay for getting drunk for the first time and desperately trying to hook up with the girl, saying something like, "Don't leave me, I'm dying," while vomiting into a trashcan.
Funny enough, while he bashes Jay and Mike he says something along the lines of, "I can't say anything bad about Rich Evans." After the incident some fans started joking about the whole thing by making mini-memes out of "I'm dying [girl's name]" and "Mike is a racist."
It really just sounds like your typical teenager/early-20s drama between friends, except Jay and Mike moved on and Gilchrist still has some bitterness about it.
Edit: Yeah, that graphic above goes into more detail.
