Another update -
V3B20r:
+Fixed the problem with bots not trying to seek the cover while reloading the weapon.
+Changed the selection of task ENEMYHUNT and SEEKCOVER.
+Improved yet the aiming for moving targets.
+Fixed bug with pushing away bots on the edge of the roof - they shouldn't fall down now.
+Cleaned the code (exactly some functions are splitted to let me easier find a specific code).
+Fixed bug with bots throwing nades in some random places.
+Fixed bug with bots looking at the wal for longer time.
This is a release candidate 5 for the official release. This version should also fix the problem on that video movie from de_dust map, but I couldn't see if that really helped or not.
As usually, please, leave a feedback if this version is really better than previous one and - if it finally deserves to be the official one.
