It happened twice now playing with my brother, my brother is hosting the world and as we have a lot of mods he has ran out of memory twice and the game crashes, it is alright as we can get in the game again, but we can't find the vehicle anywhere, not even where it was placed the first time, these aircraft are like a crucial part of our modpack as we like to explore the world while transporting our inventories in the aircraft but as the game crashes we lose everything and we have to basically start from zero.

I don't think it is necessary to list the mods we have. Thank you and i hope this gets solved and it doesn't happen to anyone else

or maybe it is necessary, we have some optimization mods like ferritecore and some more
