loot in custom building isnt spawning even after 2 days

[23p23 41 1]

Hello 2 days ago i basically deleted whole inside of VMC in DayZ Editor and built my custom "VMC" from scratch. I followed method with export loot data in init.c...but even after 2 days i am still not getting any loot in 99% of buildings i placed. 

i also rebuild krasno and balota airfield but loot spawned. Of course i didnt use same method like i used for VMC. I exported data to mapgrouppos.xml straight from DayZ Editor and put it straight into default mapgrouppos on my server but i thought since i deleted every building inside of VMC its better to use init.c export loot data method but its not working.

Any reason why is this happening?

Does it take time to spawn loot? I checked mapgrouppos if it actually recognizes my building and it does.
