It's been a while since I was the maintainer of TweakScale. I suggest you send this to lisias.

Also, they will probably need more information - preferably a step-by-step to seeing the issue, list of mods installed, and you might as well upload ksp.log on gist.github.com and link it - the log is basically always needed.
