Unfortunately, this plugin doesn't work properly for me (AMXX 1.8.1).
I have found two similar bugs.
1. When server is started, none of cvars isn't adjust to the first map. After changelevel all cvars works fine.
2. For example I have 2 settings for cs_ and de_ maps:
===============
[ cs_ ]
mp_roundtime 2.5
[ de_ ]
mp_roundtime 1.75
===============
If the map is changed from cs_assault to de_dust2. mp_roundtime isn't changed (still 2.5).
After that the map is changed from de_dust2 to de_aztec, mp_roundtime is changed to 1.75.
All configurations adjusts only after second change
