opening trigger editor crashes TFT but not ROC world editor client.

[Zackiskip]

I got access to an old wc3 ROC custom map with around 490 triggers, when i open it in the ROC editor there is no lag whatsoever, but when it is opened in the TFT editor it slows to a screeching halt then proceeds to crash the whole thing.
I have two versions of the map and both do this.
one version has models/spells that are from TFT and the other map does not.
