Reverberation capped at 3

Description
Generate a high-frequency sound wave and place it up to 10 cells away. If an enemy touches the cell, it will explode, splitting the damage it causes across all enemies in a 3 x 3 area. If nothing comes in contact with the sound wave, it will explode on its own after 10 seconds. The sound wave can be attacked and destroyed by ranged or magic attacks and an [b]unlimited number[/b] of Reverberations can be set on the ground at any one time.

Problem:

Currently, the game is capping the amount of reverberations on the ground to 3. Would it be possible to look at this? I think the script limiting it to 3 can just be removed, so long as it can be confirmed (not positive >w<). I don't have any official servers unfortunately, so if anyone else could confirm/post other sources that'd be great as well.

Thank you very much!
