It was related to that. COMBOSDM worked differently than the others. It didn't zc_max things up to 0, it didn't subtract one from the map number, and it didn't validate the given map and screen numbers at all. The crash was because it didn't check whether the resulting screen was greater than the total number of screens. Fixing that didn't require changing the others, but the inconsistency annoyed me.
That was a mistake. Turned out I fixed a problem that hadn't made it into any released builds. Actually, it was an error in that change in 1799; it originally checked scr<MAPSCRS rather than sc<MAPSCRS.I also do not know what specifically you changed for this log entry:
* Fixed Game->Get/SetCombo* failing on maps greater than 1. ( Saffith, 2016-02-05 14:29:20 )
It's still up, yes. You'd have to talk to DD about access.Are the old SVNs for the source still up anywhere, so that I can review changes that occurred prior to the code going up on GH?
