When using IC2 Classic with Immersive Engineering
Some textures stop loading
Separately, this problem does not arise.

The problem is reproduced even when only these two mods are in the assembly

Can confirm this issue

I found what the issue is.
Will be addressed with the 2.0.3 patch
ETA for that is early next year (goal is 9th)
Sorry but atm on a coding break (just looked at the code for 5 seconds and understood what the problem was)
And during the christmas time (in 4 days) I won't be home until january.

Thank you for the report.
