1. weird sea stuffs placement bug
me and my most of friends cant place sea stuffs like sea yard and fish farm. it is odd that we could place them in the player's house. only few ppl like 2 person in our server could place sea stuffs
2. walrus wont drop tam
we could only buy tam from the hat shop, which took us a long time
3. fountain of youth
i have never witness how exactly the fountain would crash the server, but my friend did and he said that he "picked" the fountain. (update, it seems it is because player pick the fountain and then jump on boat will cause the crash)
4. trawl net
my friend crashed the server 2 times and she says first time it is because she put the trawl net into her backpack and second time it is because she picked up the trawl net from the boat. and we have never touch the trawl net from that on.
5. sealnado on the pig island
not sure how this would crash the server too, my friend was on the pig island with the pig queen and he have encountered the sealnado and server crashed 2 times just because my friend was there.
6. performance issue
we have a really mighty server which could support 10 players playing through 2k dst days. but it seams we have lag spikes even with only 1 player in the server, which happens like every 2 or 3 minutes there will be a 1 second lag spike that the server will "freeze" for one second.
7. sealnado in the base would lag the server really bad
if sealnado spawn in the base, not many things on the ground but we have alots of statues and buildings in the base, the server will lag really hard that is completely unplayable.

i do enjoy playing with this server mod still and i think you guys did a marvelous job porting 2 dlc content into dst. i hope my feedback could help you guys improve the mod even further and this mod could get more popularity.
