FacorioExtended-Plus-Transport v1.01 and Krastorio2 v1.06 are incompatible.
Error while running setup for entity prototype "pump" (pump): next_upgrade target (pump-mk2) must have the same fast_replaceable_group (pipe != pump).
this occurs when using only those two mods, not even with Upgraded Gas Generator.
With Upgraded Gas Generator the error is:
Error in assignID: item with name 'pipe-1' does not exist.
