event drops compromise traditional quest based rebirth process

the event items are character bound, not store-, trade-, drop- or sell- able and not 0 weight and I am unable to get rid of them in any way. due to this the progressing with the rebirth quest became impossible during the event time.
i don't see the point why storing and trading these drop items would be in any way harmfull, but i will not question your decision about it,
but please make it possible to discard these items in some way if that is our will, im fine with either sell for 0 zeny or drop able.
