Caravans never leave home tile on map

[dereksmods]

I've sent out three separate caravans and they never leave the tile.  They exit the map and food is consumed, but they don't actually leave off the home tile.  Then I make them come back, they do so instantly, and all the colonists are starving.  I send them as 2-3 colonists with 1-2 muffalos.  I've tried splitting the caravan as well, but they still never leave.

You need to ensure the caravan isn't overloaded (this tends to happen if the caravan forming/loading process is interrupted and you try to form another).  Check the gear on the world map, if there is more weight than your caravan can hold, it'll be immobile.

Also ... do you actually give your caravan a move order/destination?  With your caravan selected with a left click, right click somewhere on the world, like a friendly colony you'd like to trade with and order your caravan to visit them.

Please attach a savegame and/or screenshots.

My caravan is carrying less than 30% of their load (muffalos are carrying everything, just packaged meals and medicine), I've tried different destinations both friendly and enemy.  My colony just got hit with the plague, so I have to patch everyone up before I try again!

This is where they stay, never moving forward.  As you can see, no one is hungry or tired.  Mass carried is 75.69/252 kg.  No matter what destination I pick, they don't move.

I am getting this in the debug log:

"System.NullReferenceException: Object reference not set to an instance of an object
  at RimWorld.Planet.WorldPawns.WorldPawnsTick () [0x00000] in <filename unknown>:0
  at RimWorld.Planet.World.WorldTick () [0x00000] in <filename unknown>:0

I think this has to do with mods I had enabled and then disabled/uninstalled?

That system.nullreference error is happening constantly.  In just a few seconds, it racks up over 300 errors.  Here's my logs: https://gist.github.com/HugsLibRecordKeeper/2285fee1972bd90c36734963d6547073

Any resolution? I am having the issue, too.

Since between the last and your entry is a new release.

You should include, your modlist, error-log and maybe a safegame, to give people at last a chance.
