I gradually added the mods to the game and did a reboot as per this order:

Harmony
Core
Royalty
Humanoid Alien Races 2.0
Androids
Android tiers

They all rebooted without error until I added Android tiers - I get this error on the main menu when I added the mod:

Moving this to the right mod discussion area here:

Sorry for posting in the wrong place! I'll leave this here for a bit so other folks don't make the same mistake as me.

I'm having the same issue. This wasn't happening about 10 hours ago when I was playing the game

Does anybody know if this is compatible with Robots++?
