Regarding "Unknown property/flag" errors

Firstly, Zandronum is several versions behind ZDoom and GZDoom. A lot of new Decorate additions in (G)ZDoom aren't even in Zandronum yet, so Zandronum will spew an error and won't start. Try it in (G)ZDoom instead. Also, to people who submit things here, it would be best to say if it works or doesn't work in Zandronum, for those forum users who can't read global announcements.

Secondly, if you get these errors in ZDoom or GZDoom, try updating your version of these engines to the latest available official release. If that still doesn't work, try a recent development build, BEFORE you post to complain that it doesn't work.

Here are the links:

• ZDoom ( official release | development build )
• GZDoom ( official release | development build )

(Note: I did some changes to the post, changing Skulltag to Zandronum and adding the source ports links.)
