I was almost done laying out my board when I tried to fix one of the DRC errors by making a larger thermal pad on a transistor. I changed the selfmade package for this transistor, replaced the transistor symbol in the schematic and thought the corresponding package in the board would update, but it didn't. I had both the schematic window open and the board window open. I think I had another schematic + board open at the same time, but I don't know if that could be the reason why the forward and back annotation failed. I ran the ERC and got the one consistency error shown in the picture below. I have tried a couple of things without sucess:
1. Changed the transistor package back to the original and updated the schematic again.
2. Tried to replace the "old" package in the board with the new one. Then I ran the ERC once again and got about 10 new consistency errors. I used the undo and now I am back with the first error shown in the picture.
I know that one solution is to delete my layout and make the board all over again, but I really don't want to do that. Is there another way to solve this kind of problems?
Thanks a lot!
