Why is 'Plugin loaded' spat into the output during playtesting?

[skewercase (crossfade)]

i could imagine why my plugins might tell me they’ve loaded when i boot up studio, but for me the warnings only occur while playtesting the things i work on, whether it be something like a physics-based sword fighting game, a visual novel, or a prop hunt game. it doesn’t really bother me much. i just want to know why it happens

(this screenshot of the output was snapped on a plain baseplate. all i did was open it and press play)

Are you sure it isn’t from one specific plugin of yours? Try disabling all of them and re-enabling one-by-one to figure out which one it is
