That doesn't make sense.... Last time I checked, 5zig was in the "1.8.9" folder. So that would not affect 1.11.
So I can check tomorrow if 5zig updated and put itself in the main mods folder, because sometimes it'll do that, but I thought I checked my mods folder.
Either way, that could be the issue, so thanks for the tip. I'll be sure to check.
