So I have Minions-1.11.2 plus the config, and using forge-1.11.2-220.127.116.118 everything up to date.
Luckily I don't get any crashes but I'm having 2 major graphical glitches, one is that the minions appear as pink and black (typical colours for graphical glitches) and the second is that sometimes they just completely disappear but you can still see the blocks being broken, so they work but with heavy graphical issues.
The invisible minions is an old bug, the pink-and-black "missing textures" is a new one. AS knows about both at this point; the second one is likely to be fixed in the next release, because its cause is known. The invisibility is something he's been struggling with for many versions, no clue when he'll manage to nail it.
