2.973 Error ModManager.cpp:1558: Failed to load mod "space-exploration": space-exploration/data-final-fixes.lua:108: attempt to perform arithmetic on field 'max_health' (a nil value)

That looks like a space ex bug from the message. It reads like they expect an optional value to be set, and apparently my mod doesn't set it, so space ex crashes rather than handle it nicely.

Hi, I checked with the SE team and they stated the first error will be fixed in the next release but there is a second error that is popping up. I posted the second error and their response to it. Not sure if this is something you plan on working on since mod compatibility isn't guaranteed any mod but I figure I would post what their dev team stated. I am not sure when their next release is planned to address the first error.

"Failed to load mods: entity prototype "railway_tunnel-invisible_signal-not_on_map" (rail-signal) collision mask does not collide with entity "rail-chain-signal" (rail-chain-signal).
rail signal collision masks must collide with all other rail signals.
railway_tunnel-invisible_signal-not_on_map modifications:Railway Tunnel > Space Exploration
rail-chain-signal modifications:base mod > Railway Tunnel > Space Exploration"

"It can be fixed by that mod adding an optional dependency on SE (so that it makes its collision mask changes after SE), or by moving its rail-signal collision mask changes to data-updates."

Yea this second error I am sort of not surprised by.
They are correct in the resolution, however, this would require me to test it with that mod to confirm it all works as expected and this change hasn't broken anything else on my side.

If this mod ever becomes active again and not just a proof of concept then I would address this :)
