Yes I've downloaded the 7.99.17 which is the same than front page I guess.
The post before the oil mention are only about 1.8 so I'm not sure it will improve the situation.
I'd say the issues started around the time where I started to regularly upgrade BC in 7.99.17+, although it did not caused issues until one day I could not start MC again while it worked perfectly the day before.
At first it was just some parts of packs (see here for forestry : releases-for-mods-f9/forestry-t147-s90.html#p39031
) and then whole ressourcepacks like thermal or Project:red, and now the mods .jar.
I've made a fresh install and cleaned all config files, no changes.
There's a high probability that the version delta is causing this so I'll try to remove specifically the oil textures in the pack to see if it works better.
Deleting all files in the resource pack referring to oil does not change the issue
Still pink if I load with useSwappableSprites setting to false, still crash if I load with true
After asking at BC support, the lead dev confirmed that it is expected for the oil to be pink with the setting to false as it is coded this way. He suggested the following to correct the issue:
"you can technically fix it by making a custom resource pack with all ~30 fluid textures"
"as in, you have to make one yourself which includes all 30 texture files, rather than the current method that generates them all from a single one"
Would it be something easy to do ?
