This is a fix to an issue when trying to unsubscribe/subscribe to Workshop mods and they dont disappear/appear in the game.

UPDATE: So I ran into this issue again and the old fix did not fix it this time however I think I may have found an actual fix... hopefully.

1.
Go to:
"C:\Program Files (x86)\Steam\userdata\<YOURUSERID>\ugc"
Delete "653930_subscriptions.vdf"

2.
Go to:
"C:\Users\<USERNAME>\AppData\LocalLow\Lumbernauts\TinyTown\Internal\Workshop"
Delete the "Subscribed" folder

(An easy way of getting to appdata is to press WINDOWS KEY + R and type "appdata". It also might be in AppData\Local for some people.)

3.
On the workshop unsubscribe and resubscribe from all your mods.
(adding them all to a collection makes this easier)

4.
Relaunch the game and it should say "Processing Workshop Items..."
Then it should be fixed!

CHECK THE NOTES BELOW FOR MORE INFO.

• There seems to be limit (around 300) about how many items you can have before the game stops showing them or starts having issues.
  
  
• The "Subscribed" folder is where the items are stored for the game to use. Deleting this folder basically ensures that they all get removed before resubscribing.
  
  I still have no clue what causes this, maybe too many subscriptions? Even unsubscribing from all mods and uninstalling the game won't fix this. Only messing around with steam ugc seems to work.
  
  If none of this fixes anything or helps you then comment I might try to help but I'm nowhere near an expert so don't get your hopes up lol.
