Inconsistent cost when quick-building electrified rails

Quick building a 100 tile long electrified rail segment using the click and drag unity tool displays 112 rail tiles. The plan UI displays the correct resource and unity cost.

different result on diagonal rails

Ok, yeah, something is definetely borked over here.

The item counts that are shown when area-selecting
the tracks is for some reason higher than it is supposed to 🤔.

But the required Unity popups are correct (according to
the item counts that are being displayed at the same time).
First screenshot set:
(100 + 100 + 200) * 0.05 = 400 * 0.05 = 20
(112 + 112 + 224) * 0.05 = 448 * 0.05 = 22.4 ~~ 22.3
Second screenshot set:
(116 + 116 + 232) * 0.05 = 464 * 0.05 = 23.2 ~~ 23.1
(100 + 100 + 200) * 0.05 = 400 * 0.05 = 20

i just noticed that this also occurs when deconstructing electric rails

so, you can just build by trucks and destroy by unity and get free resources? 😁

with full deconstruct refund? maybe. ill sandbox it tomorrow
