I built 6 water purifiers on the foundation and started cooking salt water on it and after sometime 2 out of the 6 water purifiers did not have any water cans on them. They were gone without me doing anything. I thought may be I had removed them and forgotten so I looked in my inventory and chests but they were not even there. This thing happened 2 times. Then I removed 2 them and built 4 more water purifiers on the floor above the foundation and I had 4 of the previous ones on the foundation. Then the shark attacked so i had to go and then when I came back on the above floor, poof! 3 of the 4 purifiers were gone without any trace.
Now I cannot keep more than 5 purifiers on my raft because of this and as my raft is pretty big now so I have to go all the way to where I put my purifiers whenever I get thirsty.
Please look into this bug.
I use windows 10, 64 bit PC and I downloaded the 64 bit version of the game. This issue started to appear when I downloaded the Version 1.04 update.
