In 0.15 the game crashes if i try to open Auto Research.

Error while running event auto-research::auto_research_toggle (ID 70)
Unknown style auto_research_list_flow
stack traceback:
auto-research/control.lua:238: in function 'toggleGui'
auto-research/control.lua:477: in function <auto-research/control.lua:475>

This is a really peculiar issue and I have no idea how you can get this error.
I suggest you remove AR completely and reinstall the mod. If that doesn't fix it I regrettably don't think I can be of any help. The style it complains about is in use and if there's anything wrong with it then everyone should be affected (and it works for me).

Tanks for your response. I figured out that another mod caused the problem, although I have no idea how that can create such a weird error message.
