Could you attach your save?

not a Save the startup sequence before you meet the main menu

Mod list then
Something is making a copy of projectiles as part of their mod and the change isnt renamed.
At my level of knowledge its more likely to be listing the mod as incompatible as I am not yet savvy enough to know how to guard from such events.

this is the list of ones ive got that deal with teleportation

Car Teleporter: Quantum Carburetor
Fast Travel
Kuxynator's Personal Teleporter
Personal Teleporter
Red alert 2 chrono-sphere
Teleporters
Telelogistics
Transport rings

the issue seems to be between Chronoshpere and Kux personal teleporter

please rename your "teleport-destination"

Thanks, done.
I have learned a reason today.
