When the crops are ready to harvest and you sleep 1 extra month they just wither. I have seasons turned off because we play with multible people on different farms. I have only noticed that normal soybeans dont grow. Dont know if this issue happens with other crops aswell.

Haven't played with seasons off from FS19, so I have no idea how it supossed to work, did before let you harvest the crop whenever you wanted after reaching harvest ready stage? If yes, I will consider it when updating onions for the DLC release. Also will fix soybeans.
Till then just enter the multifruit/foliage/crop.xml (crop being every crop) and search for nonSeasonal.
It should look like this
<nonSeasonal>
<update startState="invisible" endState="greenSmall" />
<update startState="greenSmall" endState="greenMiddle" />
<update startState="greenMiddle" endState="greenBig" />
<update startState="greenBig" endState="harvestReady" />
<update startState="harvestReady" endState="dead" />
</nonSeasonal>
And just remove the line that makes harvestReady go dead. Looked at soybean and I have no idea why it is not growing, because nonSeasonal looks ok (of course with the last line - dead - included like most of them).
Other thing you can do is to remove the entire nonSeasonal code and will work like base-game (but more months for growth. As I told you, I tried to reduce the time for harvest for seasons off since it is already unrealistical gameplay). But for multiplayer you would have to have the same edited map for everyone.
Please respond to the first questions, to note for myself to consider in the next update.
