I bought a membership a while back (6 months ago), made it to 200 and got myself a +6 Elektra Set. A few days ago I logged onto boutcheetah for the first time in six months and I had no membership left (obviously) and was level 172, but my +6 Elektra set was still equipped and still gave me stat boosts. I've unequipped it now, but the point is that the parts should have been removed into my inventory and were still equipped.
Thx.
