Thargoids already invading the Bubble???

Was traveling thru the Di Jian system when I saw a megaship labeled with the xeno hunting tag which made me interested.

So I investigated this mega ship and found a disabled megaship w/ the green thargoid gas around it aswell as the thargoid caustic markings, nothing happened for about 3 mins then I got a message to rescue the crew with said mission attached, cant do the mission bc im in an adder outfitted for traveling. Sat there for about 10mins to see what would happened and no thargoids showed up.

This seems extremally odd, going to get my combat ship and investigate more.

Just restarted my game and the megaship disappeared from the system….
