Emergency oncidium repotting

[Cattleya234]

Hello, I hope anyone reading this had a good Halloween. I just bought my second oncidium, and saw some problems. The moss it was potted in was suuuper degraded and compacted, and had algae, bacteria, and fungus growing all throughout it. Normally I would’ve just repotted and not thought about it again, but this orchid is in full bloom. Will it drop its flowers? Is there any way I can keep it blooming? I’m potting it back up in some fresh moss, and it’s already acclimated to the light that I’m giving it, so will it be ok? It still has a fair amount of healthy roots left, and none of the pseudobulbs are rotten, so will I be able to keep it in bloom? I tried my best not to disturb the healthy roots, and cut off any dead roots that I saw. I’m also going to let it sit out for a day to let it dry a bit. And I promise, this isn’t the same oncidium as the other thread I made about mold on the roots. The store I got them from just generally tends to overwater.
