"Unable to build nodes: The nodebuilder failed to build the expected data structures"

Any idea what's causing this? I started getting this error last week when I try to save maps and it's about to drive me insane.

What port, what nodebuilder, what editor ?

Limit-removing ports, not sure, DB2.

DB2 --> F6 --> click on the Game Configuration --> click on Nodebuilder

Tip: While your map is open in DB2, press F4 and run the analyzer.

The nodebuilder appears to be ZenNode and there's no map errors. I also forgot to mention this has been happening with all my maps.

Zennode has not been updated since 2004 and therefore does not take into consideration all the features of recent port developments.

Change the nodebuilder to ZDBSP and see what happens.

If you should be using GZDoom then have a look at this post

Ah thanks, it works now!
