Constructed a blank Factorissimo building (mk1), and attempted to place it. Error message occurred:

Error while running event Factorissimo2::on_built_entity (ID 6)
Factorissimo2/control.lua:329: attempt to call field 'freeze_daytime' (a boolean value)

followed by a crash to menu.

I have a save file with this error instantly duplicatable, though it has a fairly extensive set of mods on it:

Bottleneck
EvoGUI
Factorissimo2
Long Inserters
Side Inserters
Squeak Through
The Fat Controller

Edit:

Saw post 6 days ago as fixed, will attempt to update mod.

Edit2:

Yep that fixed it.
