I placed a faucet coming off of the create:chocolate fluid and my game crashed. Also, it happened on a server so it's definitely a rendering issue.
When I tried doing it again, I couldn't reproduce it, idk. However, shortly before the game crashed, the fluid coming out of the faucet appeared completely black if that helps.

hm I see. damn I thought I fixed all that stuff for good a while back

oh were you on a server?

Yeah I was, that could be the issue

Were you using a velocity proxy server?

Well, it was a forge aternos server, maybe you know more about them than I do.

Ah I see. Wel the I'm still not surr

Well, I wasn't able to replicate it anyways, maybe it was 1/1000000 or some Optifine issue, so the bug wouldn't be worth the effort :)
Even though it's the most unsatisfying solution D:

Oh let's hope it's not an issue anymore then
