@Sean: No, actually that is hard to find a place without events, only in unfinished parts of that level.
@SE: I was thinking about it and I guess its necessary... Or I just have to delete few tigger sceneries.

But well, that could be nice to find a way how to fix it without forcing player to collect all fastfires again/without deleting events. But thanks anyway. Still, if anyone knows a better method please, post it here.
