Today has probably the best set of fixes I have ever seen:
20th july
* Improved move order validation.
* Battle enchantments expire when caster retreats from battle ground.
* New switch: --nocheatdet.
* nation mods are now properly recognized when starting network games.
* Increased maximum number of maps allowed in the map folder.
The first two fix probably the biggest two gameplay bugs remaining - excellent news I think. But the 4th one - well, I am absolutely over the moon about it. I don't imagine it means much to anyone else, but it means that the LlamaServer will be able to start games with mod nations itself. Previously I'd have to start them manually through the GUI, and that was the one outstanding thing that could not be done automatically. Now everything can be automated! w00t!
*dances*
Honestly I'm sure you'll all think I'm mad, but that's the fix I've been dreaming of. It may also be really helpful for the making mods more mainstream in the long run.
This whole patch is shaping up nicely. I am pretty excited about the new mod commands and the attention the devs are giving modders in general, great stuff .
