The Monk sphere "Boost Blockade Health" increases the health of a wall by 25%, but when placing it in range of an existing 100% health wall the wall will gain +25% max health but its current health will not change and it appears to be damaged. If you place the Boost Aura first and then the wall it behaves similarly - it appears to have the original health and max health for a second, but then only the max health increases.
This is still occurring. Just because the sphere's gone doesn't mean the bug is too. The Boost Blockade shard still produces the problem.
Whenever a tower or blockade has their health boosted by any outside effect (as opposed to internal effects within the defense's own relic, like Fortification), the newly-gained health isn't filled until the defense is repaired or replaced.
