Best guess so far from #6913 and #6926 is that optifine is breaking something to do with resource packs or the TextureStitchEvent.Pre event as I cannot reproduce it. I did add some fallback code to at least not crash in my local branch earlier today, which I plan on committing later, but not sure when 10.0.20 will be released yet with the included "patch" as there are still a bunch of other things I want to address/fix and bumping the version just because optifine is being stupid and is breaking stuff isn't really high on my priority list.

Understand, thanks for the info i will notify pack author about this conflict then (FTB Direwofl20 1.16)
