As stated, the CBH Trains Base conflicts with the LFS Planes Base. The CBH base seems to overwrite LFS Planes' "ToggleEngine" script, meaning I can start the CBH trains, but when I try to start an LFS aircraft, it gives an error message, doesn't start, and prints an error message in console. Here's the error message:

[ERROR] lua/autorun/server/cbhtrainsbase.lua:1428: attempt to get length of field 'Slaves' (a nil value)
1. ToggleEngine - lua/autorun/server/cbhtrainsbase.lua:1428
2. HandleStart - lua/entities/lunasflightschool_basescript/init.lua:481
3. unknown - lua/entities/lunasflightschool_basescript/init.lua:139

It prevents me from being able to start any LFS planes while CBH Trains Base is enabled, which is a bit frustrating, as I play with both of them quite a bit. It seems CBH is on hiatus for a while, seemingly from personal developments based on the last announcement he made, so I understand if patches don't happen for a while. Thanks for reading, I hope this can be fixed sometime soon. Good day.
