Forced Weapon Swap

Bug Report ID: #1384184460

Currently playing with 2 scepters equipped, however I'm only using weapon set 1 as the stats are generally better, however I've noticed my ES pool was lower in maps due to having been force swapped to weapon set 2 (worse focus in the set 2 offhand).

Running some simple test (shown below) it seems that if I do not have enough spirit unreserved for an extra spectre in set 1 then using a command while it has 0 charges off cooldown my weapon will swap.

Running Powered Zealots w/ Lord of Horrors allocated on the tree making 55(.88) = 48.4 spirit cost which rounds up to 49.

NOTE: Character in question is disciple of varashta with 2 djinns however even non-djinn commands seem to cause the issue.

NOTE2: Total spirit in weapon set 1 is 276. Total spirit in weapon set 2 is 316. Unclear if this plays a role.

Test 1
- Unsummon minions until >49 spirit unreserved in set 1
- All minions active in set 2 (50 spirit unreserved)
- Spam any command skill to 0 charges (Gas Arrow, Kelari's Brutality, Kelari's Deception, Navira's Embrace, Navira's Fracturing)
- Use the same command skill while it has 0 charges
- Weapon set does NOT swap to set 2

Test 2
- All minions are summoned in weapon set 1 (10 spirit unreserved)
- All minions active in set 2 (50 spirit unreserved)
- Spam command skill to 0 charges
- Use the same command skill while it has 0 charges
- Weapon swaps to set 2 (undesired)

Test 3
- All minions are summoned in weapon set 1 (10 spirit unreserved)
- Unreserve minions in set 2 such that spirit available is >49 (67 unreserved)
- Spam command skill to 0 charges
- Use the same command skill while it has 0 charges
- Weapon swaps to set 2 (undesired)

Test 4
- All minions are summoned in weapon set 1 leaving 10 spirit unreserved
- Unreserve a spectre in set 2 (99 spirit unreserved)
- Spam command skill to 0 charges
- Use the same command skill while it has 0 charges
- Weapon does NOT swap to set 2

Test 4 is very strange to me, all the tests have >49 unreserved spirit in set 2 so it has nothing to do with that I wouldn't think. Why having 1 fewer active spectre in the offhand solves the problem, I'm not really sure.
