Using BulletType=MythicItem causes huge console spam when using RLNTE Targetter

The console spam is here https://pastebin.com/AfsZNtHW

I tested this skill with and without a bullettype and with the bullettype, there is a chance that the spam happens, it is not guaranteed but in this skill that has loads of projectiles, you can see that the error will happen as one of the mtyhicitem bullets goes the wrong way, for me the bullet will go upwards as the error comes through.

Here is a video of it: https://www.youtube.com/watch?v=GXH2r59CmaE
