Thanks for reporting this crash. I don't suppose you are able to reproduce this crash? Or expand on how often it occurs, what you were doing specifically at the time? Were you setting up waypoints for a regular spidertron, spiderling, or something from Lex's Aircraft?
Did you ever use "Shift click" with the patrol remote (which replaces the previous waypoint rather than adding a new one)?
Did you ever use the "Insert new waypoints mid-schedule" buttons (https://media.discordapp.net/attachments/1002362105049120880/1305909537466749008/Screenshot_2024-11-12_at_14.57.43.png?ex=6734be88&is=67336d08&hm=02d7750fa427f9a7a5c2174e21e742af6efc27de190b1ff097ef674b52f60298&=&format=webp&quality=lossless&width=1224&height=826) or were you always adding to the end of the waypoint list?

I'm afraid I can't recall anything more specific other that I was setting up waypoints on remote view while inside the Spiderling. I will be sure to update this thread on any other occurrences.
Epic mod.
Cheers!

I've added some code that will print a warning with some more logging, rather than crashing (although I suspect if it gets to that state, it would crash before long regardless).

I will keep a watch on it.

Thank you!
