MA seems to have implemented the spawning of spaceships like this on purpose. It is part of the thrill factor that you as a miner suddenly get a strange signal and you know you have to run for it to try and get there first.
It is a bit like hunting/mining in PvP3 or 4. It creates an extra thrill. The unexpected strange signal and the dash for the button on the spacecraft is fully intended as such. The fact that others can do the same contributes to that. It creates the suspence of if you are gonna make it to be the first to push the button. If this was changed and you got a leasurly 30 minutes to loot the spacecraft were would the suspense/thrill be. It would just be another global. Then hunters would start to complain why beacons are not dropping from bots.
And although this sucks bigtime and i feel sorry for you to have experienced this, a support call to
MA will most likely result in their default answer. That they are unable to help you. Mayby if you throw it on that your enjoyment of the game was destroyed and if enough people file similar support cases that in the future something gets changed.
Someone mentioned already something similar as that someone looted an uber just next someone else while hunting. That person probably also did not find it funny at all and was also probably green of jealousy. This probably also has happend to enough miners where an other miner got a tower just next to him. But it is according to the rules which
MA created for this virtual universe.
EU is dynamic as
MA says.
What could be improved is that the spaceship would spawn inside the radius of the finder. This would give the miner a better chance and still give the thrill.
I wish you best luck in finding another strange signal soon and being able to loot that spacecraft.
