First of all, to be clear, this is not about the Covered in Dirt bug that was fixed with the S18 patch. This is a bug that’s the result of how that bug was fixed.
Intended behavior:
Explorer’s Resolve, Venture’s shield passive, is supposed to increase their maximum shields by 30 (up to 75) and fully replenish shields to their current maximum. That is how it always has worked, since the hero’s introduction over a year ago.
Bugged behavior:
Now, along with increasing the maximum shields by 30, it only replenishes 30 instead of fully replenishing them.
This is a consequence of removing the full-replenish functionality from every tick of Covered in Dirt, since there it wasn’t intended. Now, the intended full-replenish functionality is gone from all abilities, which is also unintended.
