Weapon swap issues with reduced attribute requirements nodes on tree

4,088,331,751. Bug report number
When using giants blood, reduced attribute requirement small nodes on tree next to polymathy, and weapons which need the reduced attribute requirements to be equipped (these nodes are also using weapon swap points on the set which requires them), the game will change whether or not you can use your skills whenever it loads, such as loading into a new zone or equipping an item, and periodically on its own. This disables my offhand skills unless I weapon swap to the offhand set, unequip and re-equip an item to manually reload my stats.

I have temporarily changed my reduced attribute points to apply to both trees which stops the issue, but I hope the issue can still be resolved to make full use of the weapon swap points.
Thanks

I have precisely the same issue. Sometimes it lets me swap and sometimes it doesn't.

And I found an interesting related bug.

I am short on strength to use one of my two handers but both my two handers have strength and once equipped I am fine, as previously mentioned, something about the calculation is messed up when the weapon are in the offset, or when entering a new zone.

But more annoyingly, when using a potion and despite having a different set of two two handers equipped in the foreset, if there is an issue in the offset then using the potion kills totems.

Somehow using the potions makes a global check on something which messes up with totems and possibly other meta gems or minions.
