A world tree when damaged will sometimes not show the correct damage taken. On Greystone CT7, I use world trees to protect the upper left subobjective as the EMP kobold flyers will sometimes attack it almost immediately. The trees can be positioned to take the hit instead of the sub, but the damage taken seems to increment by 1 for each hit taken even though each hit is about 40k damage. You can clearly see how much damage was taken by looking at the remaining health, but damage taken will be a low number like 2.
Repro Chance: 100%
Steps for Bug Repro:
1) Place a World Tree next to a spawn point in some map
2) Start wave, and let critters hit the tree
3) inspect tree, and note how it has lost millions of points of health but it will indicate it only took 32 damage
Expected Results: Properly track damage taken
