Even with just BI, the stacking mod, and Transport Drones, the game loads to the main menu. After adding the other deadlock-mods, I've got the error as well, and you're right: turning off Transport Drones lets the game start again. I've followed the dependency chain:
"Bio_Industries" -->
"(?) Transport_Drones" -->
"(?) deadlock_stacked_recipes" -->
"(?) deadlock-stacking-crating-bobs" -->
"? Bio_Industries"
"(?)" means a hidden optional dependency, "?" an optional dependency. That's bad: I need to depend on Transport_Drones because it changes the collision_masks of all rails it can find in data-final-fixes, so I must make sure that it has already acted before I revert that change for our rails. It's the same thing with the other mods: they all do something in data-final-fixes where they need to make sure all relevant mods have finished doing their thing.
I'll ask Klonan if he could exclude our rails from his collision_mask change (or even add a way to blacklist rail types). If he does that, I can drop the dependency and the vicious circle would be broken. Beyond that, there's nothing I can do.
