Game crashing due to incomplete experiment

I was planning to kill the CC 10 times and after the third one my game crashed

I defeated the third one and was getting the items ready to set up the forth while wagstaff was collecting the CC's energy (that new animation)

I then grabbed the restrained static + moongleam + doodad, and when i clicked to craft the struture incomplete experiment (using fast craft pin page) my game crashed.

when i reenter the map it opened exactly where i was when i crashed and i didnt' lose any progress, as it was a "save and quit". 

Not only that, after the forth defeated CC, wagstaff's animation was much faster than the previous 3 ones (which i liked).

Yes i was using mods, but most of them are visual, like epic/simple health bar and wormhole marks, tweaks to stacks and auto stack and add a slot for Backpack and Insight.

PS: it was raining.

Ps: In the .txt file I edited (what i think) the part of the crash, the very end(a bit before), cause the file was long (if needed i can send the whole file)
