Prosthechea brassavolae pseudobulb went squishy

[Havoccity]

My concern is that today I noticed the second newest pseudobulb had gone squishy and folded under the weight of the leaves. Why could this be? I considered dehydration, but its not very wrinkly and still bright green.

Its a relatively new orchid that I received a few months ago. It's growing new roots but they aren't long enough to absorb water yet.

I ended up losing the last Prosthechea I had (a P fragrans) to fungus, so I'm a bit extra paranoid for it.
