1.5.0 conflicts with Space Exploration. No conflicts with 1.4.1

What happens if you disable all of the spidertron engineer startup settings? I'm not surprised that they break SE compatability.

not sure I can, it shows a conflict on startup when both are enabled, with options to disable the conflicting or all mods. Has to do with the rocket science recipe.

Ok, I'll try and find a proper fix, but you could probably fix it for yourself by disabling Space Exploration, then turning off Spidertron Engineer's startup settings, then re-enabling Space Exploration.

tried your suggestion (disable the space tech in mod settings and then load Space Exp) with spidertron 1.6.0 and it throws this error:

35.270 Error AppManagerStates.cpp:1453: The mod Spidertron Engineer (1.6.0) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event SpidertronEngineer::on_configuration_changed

stack traceback:

Ah ok, yeah, that's just my fault. Sorry!

Fixed in 1.6.1 :)

thanks, seems to work now!
