Hi @Geez ,
Were you able to solve the problem?

Hi, @Geez there,
Have you been able to see the problem? 1.0 is coming soon and the mod may no longer be compatible.

For me there is no pop-up and the workbench just crashes when opening Zimnitra.ent
These layers seem to be causing the issue, removing them makes it possible to open the map.

Hope the devs can take a look at this issue soon

Yes it's normal, the version I uploaded was a basic crash version, if you want I can give you the version that doesn't crash and you'll get the popup, however if you click on yes, it will crash afterwards.
Even in the error logs I can't see what object or anything is making this error

So I can't find the cause of the problem

We figured it out.

1. The data structure change just deleted one of the layer files Tanin.layer
2. For some reason the loading order is messed up. GenericWorldEntity must be loaded first, but after the data structure change it was loaded later and that crashed in all the generator entities. Moving contents of Zimnitrita.layer into default.layer fixes that.

Yep thanks a lot @dedmen
