Annihilator Bug

[rcb chief]

So i got a problem

-people can do annihilator, but after they pull the lever (when its id 1946, or that), when the next team comes and pulls it too id 1945 server freezes for about 10 - 15 seconds and then they can do annihilator. but it keeps happening

this is the error it gives me (it keeps repeating while the srver is frozed.

one more thing maybe its something to do with how my annihilator is mapped, first thing is its got 7 demons placed, and in the script it only mentions six.
