Open this save in normal TPT, and do
!set type all soap
It crashes every single time for me (memory read/write error). The odd thing is that this does not happen on all saves. In case it is platform specific, this happens to me on Windows 10 x64
@jacob1's mod appears to be affected too.
It happens here too. I'm running Linux on x86_64. It's funny though, it only happens if the mechanisms are not powered on. If the mechanisms are powered for a while, it just turns into soap as it should. If they were powered and then were turned off, the crash still happens, but it takes a while sometimes, and everything is turned into soap before tpt crashes.
