Tinny Deadly Duckling

I have a problem respawning bosses too. Though, probably I made a mistake and changed the multipliers of minimum and maximum to 0.0 from 1.0. Then I thought that this may mess up with the whole system, so I changed it back, I w8d 12 hours and bosses are still nowhere to be found, then I changed the multiplies to 0.1 and waited for 1 hour and 20 minutes after I reloaded the config. Nothing! Then changed them back to 1.0. I still can't see them around. Did I cause a critical issue or smth?
