We had planted Banana trees in spring which are also good for summer but when ever sping rolled over into summer, they died. Figured plants that are good for both seasons should last the changeover. Not sure if this is different with trees though!

Since you’re playing multiplayer, better to post report there #1405384975137898524
Workaround until the fix: play the last of the season and first of the season in one session. Don’t close the game when new season begins
And if you’re on steam, host can get the backup of the previous day where trees are there https://discord.com/channels/623097219628662784/1150988964363255950
