Minions dying on weapon change and count stuck

Main weapon - minions
Secondary weapon - not minions

When you switch weapon, minions disappear, when switched back, they re-appear

Very often when changing weapon, the minions will die and respawn cooldown will start only when switched back to main weapon

This also bugs the minion count if some of the minions survive ..
And even if alive, its not possible to use their abilities cuz the game thinks they are dead

I have a similar bug/issue.
Weapon "sets" somehow switches from I to II.
If I manually switch the weapon sets, as a result, the minion counts on the icons in the left upper corner increase by +1 for each switch weapon action, but the real (visually) minion count remains normal (as expected).
I weapon set:
Main hand - wand, grants skill: level 2 Bone Blast; +1 to level of all phys spell skills.
Offhand - sceptre, grants skill: level 2 skeletal warrior; incr spirit, + max mana, AND +1 to the level of all Minion skills.
II set:
Main hand - wand, grants skill: level 1 chaos bolt.

Right now I also get game crash after swap weapons.
