As of revision r1054, TGRDM3 project (as a whole package) is no longer compatible with GZDoom 1.5.0 - which Zandronum 2.0 is based on (or parent: ZDoom 2.5.0). As I wish to continue forward and not backwards, I can take advantage of newer features that is provided with GZDoom and ZDoom, but by doing so, there is going to be a ripple effect for ports that are not up-to-date - which in this case, as of the time writing this topic, is Zandronum.
Possible Resolve - which is going to be nasty:
- What You See Is What You Get Compatibility Patch
- Create a subordinate patch wad file that reverts the inner-core of the project to work with GZDoom 1.5.0 foundation.
- Bugs: Ignored; only important crashes will be reviewed.
I am still thinking about this situation, but at the time being, WYSIWYG seems to be the better solution at the present moment.
