I'm using Aternos to host my minecraft server for a local discord server and the latest Forge update put Redstone Pen outta commision at this time. Here's part of the log I get when it crashes.

Hi, ty for the hint. There are some changes in the Forge ongoing. The Smiths do some clean-ups and migrations fitting to the new MC version, as long as not many mods are on 1.19. So we need to given them that time. I'll check what I can already update or fix ;). Cheers,-

Hi again - I have pushed redstonepen-1.19-forge-1.0.13 with a Forge update. I hope that does it for this MC version ;) Cheers,-

Nope, gonna need another update post forge .94 (they changed something, again).

Oky, pushed it to Forge 41.1.0, it's already on Curse, can you give it a try? Cheers,-
