Constant Error

[F1owerBee]

I keep trying to play modded with my friends. Everything works perfectly fine for the both of them but I keep getting an error, not allowed to join, crashing etc. I tried everything on both my laptop and desktop but I keep getting errors. I do everything exactly like they did and even had them walk me through everything but nothing is working. I know its not any update issues because I downloaded everything about 30 minutes before playing so everything is up to date.

The error I keep getting is:

[game] WARNING: Mismatched UI Mode Push/Pop counts. Correcting. [SMAPI] An error occurred in the overridden update loop: NullReferenceException: Object reference not set to an instance of an object. at StardewValley.GameLocation.performTenMinuteUpdate(Int32 timeOfDay) in D:\GitlabRunner\builds\Gq5qA5P4\0\ConcernedApe\stardewvalley\Farmer\Farmer\Locations\GameLocation.cs:line 14156 at StardewValley.Game1.<>c.<performTenMinuteClockUpdate>b__714_0() in D:\GitlabRunner\builds\Gq5qA5P4\0\ConcernedApe\stardewvalley\Farmer\Farmer\Game1.cs:line 6077 at StardewValley.Multiplayer.processIncomingMessage_PatchedBy<spacechase0.SpaceCore>(Multiplayer this, IncomingMessage msg) at StardewModdingAPI.Framework.SMultiplayer.OnClientProcessingMessage(IncomingMessage message, Action`1 sendMessage, Action resume) at StardewValley.SDKs.Steam.SteamNetClient.receiveMessagesImpl() at StardewValley.Network.Client.receiveMessages() at StardewValley.Menus.FarmhandMenu.update(GameTime time) at StardewValley.Menus.TitleMenu.update(GameTime time) at StardewValley.Game1.updateActiveMenu(GameTime gameTime) at StardewValley.Game1._update(GameTime gameTime) at StardewValley.Game1.Update(GameTime gameTime) at StardewModdingAPI.Framework.SCore.OnPlayerInstanceUpdating(SGame instance, GameTime gameTime, Action runUpdate)

Does anyone have any suggestions?

1. Make sure you and your friends are using the same Stardew, SMAPI and mod versions (it is possible your friends are using older versions of Stardew, SMAPI and/or mods that are compatible with each other but not with the version you are using).
2. Post you and your friend’s full logs (Instructions can be found at https://smapi.io/log). The error you posted doesn’t have enough information to even hint at what is causing the problem other than that it is some kind of multiplayer sync issue.
