Submitted on Holodeck as ticket #2,853,424
The expose chances of many science and engineering abilities were accidentally halved from 10% to 5% when the expose chances of primary weapon attacks were halved. Although most of the affected abilities were fixed in the patch to Holodeck on September 25, 2014, Nanoprobe Infestation was not fixed. The tooltips for Nanoprobe Infestation still say:
5% chance: Expose target for 8 sec
(*Expose Chance reduced by half on Primary Attack)
To reproduce the bug, follow the steps below.
1. Log on to a science captain who is at least level 34 and has spent at least 209,000 skill points.
2. Hover your mouse pointer over the tray icon for Nanoprobe Infestation. Read the mouseover tooltip.
3. Press P to open the powers list. Scroll down until you see Nanoprobe Infestation.
4. Click on Nanoprobe Infestation and read its description.
