Using SCIM breaks modular stations unfortunately. When I asked over on their discord they suggested that the mod author can reach to Anthor and he can add support if you desire.
The issue I encounter is that the stations become "disconnected" from each other when the save is edited in SCIM
However, this isn't a bug, but a request, as the mod itself works properly and I don't know how much work if any is required if you want it supported by SCIM.
