The crash in the image shown below will happen every time a specific developer command is used:
flushui

This crash was introduced with the *.roq files fix, it didn't exist before

This command is vital to creating and updating game menus ingame, without reloading all assets.
It reloads all the *.urc files and their includes.

Menu/UI files are always ending with *.urc.
They may include *.inc files and "base/ui/bind.scr"
