IP not being saved after skilling up

I was wondering if anyone else has experienced this problem?
I have a lowboe soldier at 104 and recently managed to grab the Skawts plasma weapon from The Reck, it requires the Ranged Energy skill,and as mine was quite low at 222 I decided to throw IP into the skill in order to equip the aforementioned weapon…I did so and it raised the skill bar to full and 536, I saved and then went off to do some missions…next ding I went to do the same and lo and behold my skill was STILL at 222 and the IP seemed to have been returned…so I filled the bar again…saved…and went off to play…dinged again, opened the skill panel and my Ranged Energy is back to 222.
This is beginning to get annoying as hell.
