Hello! I love how cute Mini Trains are, and I love to use them in the Nullius overhaul mod, but I have found that, when fully pulled up to a train stop, a train with small fluid wagons cannot be filled or drained by Nullius lower-tier pumps (Pump 1 and Pump 2), although Pump 3 (which is a reskin of vanilla's "pump" entity) works fine. After a bit of sleuthing, I found that changing fluid_wagon_connector_alignment_tolerance on the Nullius pump prototypes helped.

This pull request on Nullius: https://github.com/GregorSamsanite/nullius/pull/31 is my attempt at fixing it. Is there a way I could contribute a similar change to the Mini Trains mod itself?

I already change it for the base game pump in this mod

Would it be reasonable to change it for other mods' pumps within Mini Trains code? Or would you prefer to keep that kind of logic in the domain of the code of those other mods? I would be happy to contribute some code if you are accepting submissions, but also equally happy to let it be if you would rather not make any updates. :)

I published a small compatibility mod that adjusts the tolerance for all pumps: https://mods.factorio.com/mod/mini-trains-fluid-alignment
