Trebuchet placed on T3 foundations with max decay time.
Trebuchet has MUCH shorter decay time.
At the time of writing this bug report, the decay time has been extended, so the foundation have a decay time of 336 hours.
The siege foundation and the trebuchet has a decay time of 136 hours.
The siege foundation was slightly raised before placed.
Steps on how to reproduce issue:
Create a structure that gains max decay.
Place a siege foundation on structure with max decay.
Build the trebuchet.
Note the difference in decay time with a repair hammer.
I used T3 Reinforced Foundation and T3 Reinforced Wedge Foundation to create a circle structure with T3 Reinforced Fence Foundation on the perimeter of the circle.
The circle had a radius of two rings.
I initially placed the siege foundation by itself, but it had the same timer.
To verify that the structure should be within range of other buildings with max decay I placed a Protected Torch on multiple locations where the siege foundation would be placed, and it got max decay.
I do not have any screenshots but will do that now and update shortly.
I also noticed that the decay time is the same regardless if the siege foundation is placed on other foundations.
So it’s seemingly missing the CanHazDecayBonus = true flag.
