[Mightyisugs]

Consistant crash upon saving and quitting. game freezes for a few seconds after clicking save & quit then crashes.

possibly related to the screenshot that the mod takes when save quitting.

I'm having the same issue in 1.20.1. but mine might be a mod conflict? Although with what I don't know.

So, from some digging its caused by a Null Pointer Exception when taking a screenshot. Funnily enough, they fixed it for version 1.21.2+, but I guess they haven't backported the fix to 1.21.1. If you're code-savvy, you can clone both 1.21.2 and 1.21.x branches and just copy-paste takeScreenShot() from the former to the latter. Then you can build and have your fixed jar file to plop into your modpack. It's a hack job, but it should fix the issue until they backport the changes.

I'm not very savy in that aspect. but honestly I haven't been able to play in a few months. Do you think this is something I can send as feedback to them? Or could you since you know how to say what's actually wrong XD If not, could I just forward them this email?
