Please DE, please make this a thing. At least give the mods to Simaris if you have maxed out the event previously.
Quite a few people have probably made the mistake of dissolving their mods from the event, not myself but others I know have fallen victim to this. Yes, this is due to their own negligence but I would believe most Warframe players think about this as any other item in the game. "I have a way to reobtain this so I don't need it now." There is no explicit warning that tells you that the mod you are selling or dissolving can not be reacquired.
