I feel like I made a tactical error presenting my argument hahaha
Sometimes a player leaves and the UI bugs out and mex snapping is turned off. Has anyone experienced this? I only mention it because if you have experienced it you know how incredibly annoying it is not to have that snap, which made me realize there's a chance base building could be improved if snapping was more common, not just restricted to mexes and hydros.
Adjacency and occupancy make the most sense as things to snap for, if it can be done at all.
In other words, this is a solution in search of a problem rather than the other way round, @arma473
(The fix for the UI breaking I mentioned is just clicking the ACU select button on the right side of the screen, by the way)
