As the title suggests, I have a bug of objects on a layer in my file becoming locked. This happens on one layer, so I go back into an older file to copy-paste the older version of the now-locked item back into the current one and then I delete the old layer. What happens now is that the locked objects on a layer now moves on to the next layer so the next set of objects becomes unselectable. Not only can I now not select the items anymore but the layer can also not be deleted anymore.
When this happens, the items become a dark grey and I cannot select them. The trouble started when I tried to edit a block in place. I now removed all blocks and re-imported the original block, but before copying it, I exploded the block so it wouldn’t bring any corrupted data with it.
It keeps happening. Eventually I managed to solve the issue by unlocking everything but I am sure that the software is not meant to auto-lock items by itself. Is this a protective feature, a broken file or some error in the software?
Included a screenshot of the individual items being greyed out and locked on multiple layers all visible and the layers are not locked while I haven’t even selected them in that session.
