Everytime i click right mouse button on a pipes (from Thermal Dynamics) while holding axe or any item that have the same behaviour game crashes. I don't know why this happens but it is.
I think what is happening is that game tries to "chop" the pipe but can't as there is no result from such action and it crashes.
Anyway, log is here:

crash-2020-01-02_15.15.07-client.txt

Not going to be doing any more development on 1.12, sorry.

This ain't gonna be fixed. No updates for almost a year.
