Hey! sorry for the delay in the response, question like this one moves faster on the Discord community: https://discord.com/invite/b83ykCM9Xp.
Before creating a new cabinet, you could check on Discord or the database if the cabinet doesn’t exist yet. If not you can proceed to create a new one.
If the cabinet don’t appear in the workshop, may be is a problem with the name, be sure the cabinet file name is test.zip.
If the problem continues, go to discord and ask on the ask for help channel, post your cabinet there and someone (if not me) will for sure check it out.
Regards.
