A Minor Inconvenience

In survival, summoning the Empress of Light, especially in the daytime, is not very convenient. Right now, there is a plugin which disables the placing of critters. This plugin therefore does not allow the prismatic lacewing - or the summoner for the Empress of Light - to be released upon capture. Due to this fact, in order to summon the Empress of Light, the prismatic lacewing must be killed upon sighting to normally fight it. However, if one wants to battle the Empress of Light during the day, they will manually have to trap the prismatic lacewing with blocks and wait near the critter so it does not de-spawn until it is ready to be killed in the morning.
I am not sure how this problem can be resolved accordingly. But if it is possible, can the anti-critter placement plugin be changed in order to account for this issue?
