IBD is a disease not disorder. If she has IBD she will be dead in no time, Id be more worried about a boa having IBD since they can go their whole lives carrying it. Pythons once exposed are dead in a short period of time. Your snake has spider in it, it does not have IBD.
All spiders have the potential to wobble, I've personally seen how a spider can appear to have no wobble, then change homes and develop a horrible wobble, then come back home and have a minimal wobble.
Stress appears to play a big factor in how much they wobble, he/she just changed homes, so it could be a very stressful time. Make sure your husbandry is right and she might calm down over the next couple weeks. Its quirk all spiders have the potential to show.
