Incorrect amount of destabilization in private league (hotfix 14 not applying ?)

I have been playing in the "second wind" private league (PL7782) and documenting my progress on building up a temple.

I've been stuck on an average of ~38 rooms for a little while, which I first chalked up to bad luck but after a dozen runs and actually examining the destabilization happening, I noticed that at this point I would lose 5 rooms per run to destabilization.

I did a quick check back on the main fate of the vaal league, and I would lose the same amount of rooms in a temple that has 58 rooms.

It would seem that the temple has a stable size at 40 rooms in the private league, and 60 rooms in the main league, which is exactly what hotfix 14 changed so I think it might be related. On top of that I have also noticed the bug of ropes created by viper legionnaires failing to detach, which was fixed in hotfix 24. This is just a hunch of course but hopefully that helps.
