Minion Count and Spirit Reservation Math Breaking, Weapon Swap Resets

I'm experiencing a strange bug in regards to my Minions and Spirit reservation:

Occasionally (cannot reliably reproduce cause, unsure what triggers it, but I believe it has to do with a bunch of simultaneous Minion death and revivals), my Minions will Revive in fewer numbers than they should, and stay that way until I weapon swap. My Spirit will also unallocate itself, but not by the correct amount.

To be specific, I'm currently running 3 Skeletal Warriors (level 9, 23 Spirit, 2 free) and 3 Skeletal Snipers (level 9, 35 Spirit). This leaves me with 2/130 Spirit available. Sometimes, in or after a big fight, my Minions will instead respawn as 3 Warriors and 1 or 2 Snipers. The remaining Snipers won't ever respawn, no matter how long I wait. It also changes my Spirit from 2/130 to 25/130 or some other higher number. Notably, this increase does not match the cost of the minions that are lost. A weapon swap fixes it, but that is only a workaround.

From these observations, it looks like the game "forgets" how much Spirit my Minions are supposed to cost, and recalculates it, leaving me with fewer overcosted ones until I can swap weapons to reset it again.

Here are some images representing the issue immediately after a fight where it happened:






And here are the images of it fixed, after a weapon swap resets and I get my Minions back:
