Odd Intermission Bug?

[EtherBot]

I'm not entirely sure where to post this.

I've come across a very strange bug. I'm working on a personal little wad with at least 26 different clusters (dont ask) and I've reached a point where intermissions between clusters simply fail to work. Once you get up to cluster 26 it will que up the very last intermission no matter what. That means if you have 26 clusters you're fine, but add an intermission for cluster 27 and they will both play the text for cluster 27, and so on and so on.

I'm really not sure what to do about all this. I've hit a bit of a wall. I'm hoping it isn't some hard-coded feature of zdoom or something.
