I’ve received a report that this mod or one of its dependencies changes Cerys by allowing most buildings, e.g. solar panels, to be built on the Cerys water tile, which is normally prevented.

If I had to guess I suspect it would be that the mod modifies the default collision masks for entities by overriding them, without considering that they may already have been overridden by another mod.

all collision interacting code is in data-final-fixes.lua

not 100% sure how this would affect cerys,

i suspect
elseif collision_mask_defaults[k] then
-- log("Modified default collision mask of "..v.name.." which is in data.raw["..k.."]")
v.collision_mask = collision_mask_defaults[k]

feel free to have a look as well, open to suggestions

I can mark the mod as incompatible later
