Hey again. It's been years, got back into playing with this stuff. Be more learning to do lol.
I used to be Deathbringer/RapidRunner but i dont know password i used, or have the email i used years ago..
anyhow... problem is...

You fly any ship into the sun it'll crash mud.

well after a quick look at the code you probably should add a ship_next and set ship_next to ship->next at the start and use ship_next instead of ship->next in the for loop. the ship is being destroyed when it flies into the sun and causing the issue.

Remcon is a Genius! Don't know why i didnt think of it! lol.

Fix that works then would be here to help others.

in space.c move_ship
find

SHIP_DATA *ship;

and change it to:

SHIP_DATA *ship, *ship_next;

find

for ( ship = first_ship; ship; ship = ship->next )
   {

change it to:

for (ship = first_ship; ship; ship = ship_next)
{
    // Store the next ship pointer before potentially destroying the current ship
    ship_next = ship->next;

its what i did and its working
