Blood Mage Life Remnant messes with Spirit

I don`t know if it has a hiddent cost, or it affects other spirit related things but it definetly seems to mess up spirit costs somehow, like i have 30 spirit left i apply another aura it disables itself. Or even with a single 15 spirit cost support gem, while i have 30 spirit left over, it brings my spirit down to 15 but it apparently still turns off Life Remnants because not enough spirit?

Just backing this up since it's been an issue the entire time but at least sometimes it decides to arbitrarily work. If I fiddle with the vitality support gem I have in life remnants and pop it in elsewhere, the disabled tooltip goes away even though it's using the same amount of spirit as it did before. I've noticed it really doesn't like gemming into life remnants itself which is when I usually see it pop up.

edit: just added herbalism (15 spirit) to life remnants with 18 spirit left and it was disabled. Adding it to withering presence instead enabled it and properly reduced my spirit to 3.

Bumping this.

This is cause when you're using support gems with an "Additional Spirit" cost. Life Remnants seems to have a defined 0 spirit allocation as a buff, so the Additional Spirit allocations of the support gems get added to the 0.

Equally, if you use the same support gems on a standard skill that isn't an buff, then it will not affect your spirit.

I also have this issue. The Vitality support gem uses 20 extra spirit. I have 20 spirit left. When I add it to life remnants it disables life remnants for "not enough spirit".
