Does this mod alter the offshore pump at all?

The pump ghost looks normal, but once built the pump has two connection points (the blue arrow), one about half a tile outwards from the other. I cannot connect pipes to it: the pump is blocking placement of the pipes!

Also using AAI Industry and Krastorio 2 which apparently both affect the pump.

Without the Terraforming mod, I still see two connection points (blue arrows), but pipes do connect. (With Terraforming, the pipes collide with the pump when placed normally.)

Interesting. This appears to be a problem with mods using helper entities. Like AAI's Industry powered pumps. I'll look into it.

I already debugged this. you need to exclude more flags from adding collision masks.
do you need me to send you the altered file?

Was not able to recreate.

I think the fix is already in the file, I remember making the found1 and found2 in data updates.
as it is, though it'll probably crash and burn with a mod like SE since it overwrites all belt entity collision masks.
Although, it's probably not really conceptually compatible with SE in the first place.
