When I try to upload just an .esp to Steam, I dont get the normal prompt to choose whether to manually archive or not, it automatically goes to an archive list with BSShader_DefNormalMap as the only file on the list. I cannot get to the upload dialogue. This prevents me from uploading my updated mod to Steamworks. Please tell me someone at Bethesda is aware of this.

bump

Try deleting any BSA, BSL, or CKM file with your plugin's name, then try again?

There are no .bsas or any other file besides the .esp

same happens to me..
