Its the m2 bug discussed here 100 times. Just load in taliis and save again.
Ahd how did you make the patch?
Are you sure Taliis actually saved your adts ? Sometimes if you don't "save as" in another folder it doesn't.
Oh you can ignore these messages, it's usually ok even with those "errors".You can check if the paths and spawning are ok in Taliis. There might be something wrong in there ?
Pack and send me a link to the adt. I will have a look.
