Upgraded to 1.16.0/1.16.1 and after working through a bunch of other issues connecting I now can't go to my void or mining world. In both cases I get the error message Invalid World ID set. I've tried placing a new Mining World block and it has the same error.

Anyone seen this and fixed it?

Fixed it by backing up/deleting the relevant folders in \dimensions, deleting the folders, starting the server, stopping the server, restoring the folders and then restarting the server again.
 
Which folders are relevant?
Under \saves\My DW20 World\ I see a DIM1 and a DIM-1, which I believe are the overworld and the Nether. Then there is a "dimensions" folder with appliedenergistics2, jamd, javd, rats, undergarden, woot. I take it I need to backup/remove/replace one of those.
