So, I have been farming the crap out of a planet I called Masons World. The routine is simple. Land near caves, Take a ton of Albumen Pearls, Emeril and Titanium (from the sentinels I destroy) then go to space station, sell. Rinse, Repeat.
I am in a stripped down 32 slot ship with a 31 slot suit.
Last night, when I got to the space station, and went to sell, the screen did the shrink thing as if I had not talked to the Vy'keen in the station before. After selling, I turned and sure enough, there was the interact thing without the 20 carbon requirement. I talked and got offered a new multi-tool, which I turned down.
For the fun of it, I decided to go check the other side that requires my atlas V1 pass.
When I got there it said door locked, but did not require the pass. Once inside, I got another suit upgrade and an already known tech.
They had reset. I am positive I got them before. It is the first thing I did at the station a few days ago. That means that the station resets after a certain number of trips, or a certain amount of time..... More suit slots for me.

Sentinels are both dumb, and smart.
While farming, I get the elite sentinel units almost everytime I open a pearl, which I promptly destroy, if they are in the cave. They seem to not have good pathing because if they are not in the cave, they never find their way in, meaning I can load my complete inventory and never have to battle. But they threw a surprise at me yesterday.
I was outside the cave and opened a pearl when the first two sentinels appeared. As I killed the first, a new one spawned. Everytie I killed one, another one spawned. It was almost as if they got smart enough and finally said enough is enough. After the 12th kill, I decided that that particular pumpkin patch was not worth it, I ran into some caves and waited for them to deactivate. (I farmed inside the caves).
The sentinels deactivated, I left and launched for the space station. Sentinel starships were waiting for me!!!! I guess I pushed them too far... I escaped to the station, and after 20 minutes of just waiting, they decided to let me go.... I am back farming.

The green diamond with Exclamation point seems to be kind of working on pumpkins (which hold pearls). I noticed it a few times if the pumpkin was close to me. BUT, it always shows up on ones I already opened, regardless of how far away (within the scan area)

CLONES EVERYWHERE....
While on the space station, there were three of the exact same ships, with the same alien and same cargo, all there at the same time.... As I watched, this happened with other aliens as well, but usually only two at a time... Seems there are only 5 traders in the system I am in. which reminds me, they show up on the planet I am mining at the trading posts as well.....

Ok, done with the random thoughts post...... Time to farm.

Yea, I figured you have about 2 days before the stations and any global shopping modules re-stack, probably the whole thing resets (I`ve seen evidence of this myself). Personally it could be better done so it`s not so in your face. For a start there`s no need to do a whole new cinematic screen.

I have not pushed sentinels that far yet, interesting to know. In my experience they seemed to stop at about 4 floaters and a couple of walkers, didn`t realise it could get worse.

The cloned ships is awful. I hate it. It totally takes me out the game. I don`t mind seeing identical ships so much, but when you also get identical aliens then you know something`s wrong. They need to fix this asap, it looks lazy.
