Save my wispmothers

[Pennydropt]

One thing I've noticed and find kind of depressing is that the more mods I put on, the slower and less responsive the wisps and wispmothers are, to the point that they just don't move and the wispmothers don't even come out of the ground. Even the vanilla ones.

So my question is, is there a way that someone can make a mod with the original movement and attacks and attack speeds which will override anything in any other mod that might affect them? There are mods out there that change their appearance, but what I'm looking for is one that fixes their performance, if that's possible.
