Hi, I installed the latest 1.15.2 file and now when I try to interact with the control block the game freezes and crashes. I included the crash report. For now I've gone back to the previous version of the file and it doesn't crash.

What Forge version are you using?
Could you try redownloading the latest version, because I reuploaded it after a few hours to fix this issue. You might have beaten me to it when you downloaded the latest version.
Edit: I can see the forge version is up to date, so that shouldn't be causing any issues.

Same here, both client and server.

In fact, v1.2.12 is also crashing the same way.

Do you also happen to be using Packed Up?
Edit: If so, could you see if updating Packed Up fixes it?

@traveldesign You're crash is unrelated from @lebanni, does updating to version 1.2.13 fix it?

Doesn't crash anymore with both latest versions
