Optifine 1.15.2 for forge just released but the game crashes when loading a world. I looked at the crash report and saw Refined Storage was causing it (I'm not sure about this it could also be optifine but I decided to post an issue here first). I tested this on a server, not in singleplayer. Using OptiForge and optifine 1.15.2 pre-13 did work.
The game crashes when loading a world.
Does this issue occur on a server? [yes/no]
Yes

Same issue, instant crash when placing a controller in the world.
Edit: correction, when placing any block from refined storage.
I can also confirm that it crashes upon loading my world that currently has 2x grids, 2x controllers, 2x disk drives, and 12 various drive items within it.
Updating to 1.15.2 Optifine-pre15 fixes this issue.
