Campaign_RND.mis editing. No difference?

Hi

Im doing major changes in Campaign_RND.mis and start new career but the changes doesnt seem to make any effect.

I run stock 1.4b SH3.

I change all taskforces in the file to

DelayMin=6 (was 60, not sure what this is, also tried not changing this)
DelayMinInterv=3000 (was 30000)
SpawnProbability=100 (was 20-80)
ReportPosProbability=100 (was often 20)
GameExitDate=19450620 (something higher that stock)

Still i see no more taskforces at all. I track the simulation with SH3Gen on max so i dont really miss anything. Still the sea is just as scarsely populated as before i modded the file.

Can it backtrack to saved original file somehow if something is ill-written in the file? It doesnt crash on startup so it appears to be valid. Anything else i need to change to make it work?

Thanks
Erik
