Apologies in advance if I'm flogging a dead horse here, couldn't find anything like this in 'known issues' and this forum is a bit of a mess. So, the specific scenario I've verified this in is using Snipe (with and without Overcharge) against pairs of identical structures. Either way the same damage is done (and this was with level 4 Snipe so the difference should have been huge), so one of a few things has to be true:

1) The tooltip is wrong and Snipe doesn't do more damage in Overcharge.

2) Overcharge is bugged and isn't affecting Snipe as intended.

3) Overcharge is bugged and was still affecting Snipe on both shots.

4) I'm missing an unlisted characteristic of Snipe with regards to structure damage.

5) I'm a blind idiot.

Anyone else having issues?
