The game crashes whenever I click on LC's config buttons

Here is the crash log: https://paste.dimdev.org/vinotaduno.mccrash

Here is LC's github: https://github.com/LambdAurora/LambdaControls

Fixed as of 1.2.2

The link is dead

Hmm, it works for me, try the issues page https://github.com/LambdAurora/LambdaControls/issues

the crash log is dead, not the github
