Try scrolling to another row which it is already on. I found it on row one.. tried putting another copy of it there which disappeared. Not going to test removing the one that actually stays there. Guessing when it auto adds then you can't do anything with it?? I don't have any issue with other abilities.
Bug fixes are a joke. You fix the 'game breaking' bug when exiting the Mountain Pass because you are lying down but don't fix the actual mission which won't complete lmao. Think the fix to that was in the patch notes 2 patches ago but still the same thing. Thought I had a workaround but kept failing.
No, it's not just you. And it's not just a particular power or limited to just space or just ground. I have the MACO Heavy Graviton 'moving' from one tray to another or just going missing as well as the Borg set powers.
On the ground, the same thing happens with STF set powers. Here, they even get swapped around (set's 2nd power swaps with set's 3rd power/etc).
Powers that disappear, or get swapped whenever you enter a new zone. Seems to have started happening right when the Winter Event started. Must be that snowball/half-melted thing gumming up the works.
Now, every time I zone, I check the powers tray. It's inconvenient but I'm already used to having to redo the space powers tray whenever I switch/rename/discharge a ship anyway. Just part of the charm of playing STO.
