To my knowledge, 227 patch did not and does not pursue the goal of fixing the stock maps (except for a couple of places).Bugs and glitches detected include:
- DmAriza (botplay, still trying to fix this, at least they go for the Flak Cannon now -ToDo: Shield Belt and Invisibility-)
- DmAthena (bots won't go for the Shield Belt, the Fruits or the Flak Cannon at the Lava Lake, nor the Cloaking Device or the Stinger at the Secret Chamber; solved the former, still problems with the latter)
There are several mods that fix standard maps for cooperative game, but I'm not aware of any mods that would fix DM maps, except my own UGoldFix which fills some deadly BSP holes on DmAriza and DmDeck16. I didn't pay attention to issues with bots, because I didn't find playing with them interesting anyway. Besides, I didn't know that it's possible to add new paths for AI without modifying the map package, but now I see that 227 allows to add missing PathNodes and connect them with other NavigationPoints using UScript only - hence, the fix can be implemented just by adding a few lines of code to a mutator.
