GregTech Modern Bugs Fix

Elimination of critical issues in GregTech CEu Modern

Development of GregTech Modern for version 1.21 was halted for a long time, leading to the accumulation of numerous bugs — both minor and critical. This mod was created to address this situation, allowing players to enjoy GTM 1.21 without constant crashes.

Technical implementation

The mod uses Mixin technology to make changes directly to GregTech Modern and LDLIB code, enabling effective troubleshooting of discovered issues.

Important warning

This mod was created exclusively to ensure stable operation of one specific save file. Therefore, the correction methods used can sometimes be radical. We cannot guarantee the absence of new bugs or complete compatibility with all snapshot versions. We strongly recommend regularly creating backups of game saves when using this mod.

Frequently asked questions

Why not make fixes directly in GregTech Modern?

Unfortunately, working with the GTM project constantly encounters problems with building through Gradle. This makes direct development and creating pull requests impossible. Creating a separate addon mod solved this problem — now code can be properly built, compiled, and run.

Why hasn't XXX bug been fixed yet?

At the current stage, fixes are focused on bugs that seriously affect gameplay. Less critical issues receive lower priority.
