Hey there, txAdmin creator here.
There is no such a thing as a limit of resources in txAdmin, just a warning in the diagnostics page and one other page to suggest this might be the cause of some issue that happened, but in no way txAdmin limits how many resources do you have.
That being said, it’s obviously always a good idea to be mindful of how much stuff you add to your server… no player is gonna sit waiting 15 minutes to download every asset if they can just join another one of the 27k servers out there.
