The fairy satchel bag is causing XNA issues for me. currently testing potential fixes client-sided but since not much people are posting here, I'd thought I make a mention for now. will post again if I do find a fix.
will note that I'm not sure if it's an item in the bag causing an issue or that specific bag's UI itself. just started occuring and will post more soon (will screenshot if it occurs again)
Editing to mention it's an issue with alchemist satchel
View attachment 228501
This happens every time I open the Alchemist Satchel
Also should mention Tmod is v0.11.5 and the Portable bags is the latest version from mod browser.
The problem is occuring as of last hour and not after I updated it 4 hours after it was updated in mod browser.
It occurs even without other mods (as stand-alone) but will mention mods used that worked with it anyways (no changes to any of the mods prior or after issues)

These functioned on a dedicated multiplayer server and solo. now both are plagued by the problem for myself in solo and the users of my server.
Hope the details helped.
