The guild statue bonus issue is still ongoing. Several of us have reported this bug numerous times in this thread beginning on June 20th and it still isn’t even on the list in the original post, nor has its existence been acknowledged in any other way. The issue is not mentioned on the PC/mobile known issues list either.
To be 100% clear, the issue is that the stat bonuses that should apply to our troops when a guild task is completed to level 12 is not being applied. When the guild statue is selected from the Guild screen, the bonus does not show (it is still greyed-out) and there is no countdown timer to indicate when the bonus should expire. This is not just a visual glitch. I have confirmed the expected values of certain troops both before and after my guild has completed a task and nothing is changing in battle.
For example, my Khorvash is mythic and level 20. His spell should do magic+3 damage to the first two enemies. His base magic at level 20 is 9 and I have all 5 magic kingdoms levelled to 10 with 5 or more power stars. He should do 22 damage with no guild bonus, which is what he does. This week, my guild completed the Purple statue for the first time in a couple weeks. Both before and after this, my Khorvash is doing 22 damage, so it is clear that no bonus is being applied. The same applies to other guild stat bonuses.
I have found that if I click in and out of the guild menu a number of times, the stat bonuses will sometimes show up. This seems to be random and I can’t reproduce it in any reliable way. If I see the bonus, then go into PvP, I find that my expected bonuses apply for a single battle and then disappear again.
I am on PS4 and my guild is Crimson Sky. Other players, including @Dan_ozzzy189 have verified that this bug is present.
