Ok, you are completely right. Even if my reproduction steps cause the capacity to be exceeded as well, your cases have nothing to do with that. Just a coincidence, two entirely different things have similar results

Sorry for the confusion so far. I am deleting my first post in order to prevent further confusions

Your cases seem to be related to set bonuses. If the produced amount is too much, the game first calculates the remaining capacity as the maximum collectible amount. But afterwards, the set bonus is applied, which results to excess gain.

**Current situation:**
Humanium and/or Elvarium capacity can be exceeded by collecting island productions with set bonuses.

**Expected situation:**
Not to exceed capacity.

**Reproduction Steps**

1. Have a D000-b "Core" with Humanium/Elvarium capacity x.

**2. **Have some islands and place them so that at least some have set bonus.

**3. **Have y amount of Humanium/Elvarium where y is close to x. (y < x)

**4a.** Produce Humanium/Elvarium on islands with a set bonus of 150%, production amount being z where z > x - y

**4b.** Produce Humanium/Elvarium on islands with a set bonus of 200%, production amount being z where z > x - y

**4c.** Produce Humanium/Elvarium on islands with a set bonus of 250%, production amount being z where z > x - y

**5.** Collect the production

**6a.** Observe: Humanium/Elvarium amount ( y + (x - y) * 1,5 = x + 0,5 * (x - y) ===> (since x>y, greater than x) ) exceeds capacity.

**6b.** Observe: Humanium/Elvarium amount ( y + (x - y) * 2 = x + 1 * (x - y) ===> (since x>y, greater than x) ) exceeds capacity.

**6c.** Observe: Humanium/Elvarium amount ( y + (x - y) * 2,5 = x + 1,5 * (x - y) ===> (since x>y, greater than x) ) exceeds capacity.
