When Anti-Freeze pipes ( https://mods.factorio.com/mod/better-thermal ) and Flip dots are installed, this causes an error on flip dots' side :
Failed to load mods: Error while running setup for entity prototype "lamp-flip-dot" (lamp): next_upgrade target (switch-flip-dot) must have the same collision mask.
Mods to be disabled:
• flip-dots (0.0.8)
