This is not the same bug in that thread (i read it before i post this one), basically that bug is that one hover tooptip is mixed with another one, and is
in there from the start of the game, but i never able to reproduce it in a consistent way.
The bug here is that the normal supplies cost is multiplied by the size of the unit, resulting in unit with size 1 having no problem in their hover tooptip, but with the Ent (size 12), Golem (size 6) and Sorceress (size 4), come the problem that in some part of the formulae are added the size of the unit which must not be there.
As example are the pictures sumitted:
Ent
Unit cost: 264-------so 264 * 23 (quantity trained) = 6072 real cost which is sustracted from mainhall reserves, 6072 * 12 = 72864 value in the hover tooltip.
Golem
Unit cost: 324-------so 324 * 46 (quantity trained) = 14904 * 6 (unit size) = 89424 value in the tooltip
Sorceress
Unit value: 128-----so 128 * 69 = 8832 * 4 = 35328
