While training temporal bridge officers (and a few BOffs of other specialties) on each of my toons, I have encountered a problem. Space skill training works just fine, as does career-track ground skill training. However, in some cases I'm unable to slot ground specialization skills. I can train those skills, but clicking on the trained skill to slot it as a default skill has no effect. (The sound effect plays to acknowledge the click, but the slotted skill does not change.)
For example in the screenshot below, I am trying to slot Uncertainty Burst I as an Ensign-level ground skill. As you can see, the BOff (Lt. Leb on
Drayton@NCC-89471) does own that skill, but when I click on the skill to slot it, nothing happens.
This appears to be one of those dreaded bugs that occurs randomly without much rhyme or reason. It affects some of my BOffs on some of my toons, but not others. I've seen it happen with at least one BOff of each career track, and with all three primary specializations that include ground BOff abilities (Intel, Command, Temporal). In fact the only commonality I've noticed is that only ground specialization skill slotting is ever affected. I can slot space specialization skills just fine but not ground ones.
