[1.12.2]game crash when switching propellent at "dawn" xeon engine. also engine doesn't work

[tonimark]

game crashing whenever i switch propellant on stock ion engine ... also the engine doesn't work when toggle online (it appears to be a KSI-E and kerbalism bug since there is the label "chemical engine") to replicate simple launch a vessel with ion engine and switch it on, and press on next propellant

EDIT:after the vessel is the reloaded the issue is fixed (as long as the vessel won't reload with the engine active) however the issue still occurs if you activate the ion engine and reload the vessel

This might not necessarily fix the problem you're having, but it's a good idea nonetheless: don't put mods into the Steam controlled copy of KSP, it breaks stuff a lot; instead, make a copy of KSP and put your mods into the copy.

1. Make a copy of your save game(s) (inside Steam/steamapps/common/Kerbal Space Program/saves) and put them on your desktop.
2. If you're using CKAN, and I suspect you might be or that mod list would have taken a long time to make, export the modpack (File > export modpack) and save that on your desktop too, this will allow you to easily reinstall all your mods later.
3. Delete all mods from the Steam copy of KSP so that only Squad (and SquadExpansion if you have either/both DLCs) are left in GameData.
4. Uninstall and reinstall KSP through Steam.
5. Verify the game files through Steam (right click KSP in Steam library > Properties > Local files > Verify integrity of game files), this will make sure that nothing has been corrupted in your KSP install.
6. Copy the entirety of KSP (Steam/steamapps/common/Kerbal Space Program) and paste it somewhere outside of Steam's folder tree (e.g. desktop); this is a brand new copy of KSP that Steam can't touch and which you can now install your mods in.
7. Add this new copy of KSP to CKAN and reinstall your mods using the modpack from step 2, then grab your saves from step 1 and put them back into KSP/saves.

If the issue persists in the new copy, try asking in the KSPIE support thread, you'll get the attention of those in the know about KSPIE over there (I don't use that mod myself and know very little about it):
