Minecraft crashed when using both

This issue page is practically dead, but to give you an reply: This is entirely on TweakMyClient's end. Plus, TweakMyClient is such a small mod, standing at only ~600 downloads. It also seems to have compatibility issues with Xaero's Mini/World map.
I recommend you go to TweakMyClient's GitHub (https://github.com/Hendrix-Shen/Tweak-My-Client) instead, and post an issue there about it, as there's practically nothing on this end.

For me it works with xaeros world map btw.
I'll report this at tweakmyclient

Yeah, it works with worldmap for me as well. Just not minimap, I guess.

Also, please close this issue, as the bug is resolved. However, there's not an available release with the bugfix available for download, so please wait until TweakMyClient releases a fixed version. Thanks.

Ok
