Start levelling your paladin exp again then. Neither we nor Nexon can or will do anything for you.
I heard it's just a bug that occasionally happens.
Ow losing all those paladin levels lots of time wasted. 1 hour per transforming.
I is sorry for your lost.
To use the x2 exp transforming, you should follow these step carefully. 1st, transform right at the boss and kill it asap. 2nd, reload the map when and only when all the loot show up. Dont do it right after you kill the boss. 3rd, Click Go to Town, not Replay the dungeon.
It's a common bug that anyone can experience. I heard if you just level it back up your pally will return to it's original level.
it might be just a minor glitch or nexon had figured u werent lvling up ur trans legit so they deduct the levels. It had happend to me once.. but not with trans.. with ap.. i gotten -14ap i think.. Mayb just a minor bug.. since you still have your skills points... good thing is you can have more than 20 points for ur trans caz all ppl max at 20 points for now... so u will have 24 points.. n 4 extra when the update hits.. if you were able to lvl it to that stage b4 the update for trans
Pretty sure normal players experienced it too. Someone is raging over it at the Bug report section.
I dont get why ppl rage about good bugs.. like the dura bug... some ppl posted n nexon fixes it.. this bug might be a good thing too if it works as the way i think where you can have more points than others since the points counts by the level of your trans
