It appears my Workshop upload, “Synthia, the FTL Rebel Synth”, has been flagged as non-compliant with Community Guidelines.
I contacted Steam Support, but I received a message stating the content was removed by the developer and not Steam. I just find this a bit strange, as the model received no complaints and stayed uploaded for more than two years without issue. If it was some serious content violation, I would have expected this issue to be brought up a lot sooner. Regardless, if it is something I can correct, I would like to remedy the situation as quickly as possible.
I apologize in advance for taking up your time!
