A google search suggests that it's the mod "Real Faction Guests(Continued)" that's causing the error. If disabling that doesn't solve it, I don't know what can help you, I've had the same issue too.

I just had this problem and the fix was to edit the save file.

Search for "LordJob_TradeWithColony" and delete the entire <li> ... </li> section it's located in.

In my case, the cause was some pack animals of a trader caravan not exiting the map with the rest properly.

The error reappeared for me, i tried to do as you say but watching my savefile i could not figure the <li> ... </li> section your talking about. Tried to delete some but sadly didn't work and destroyed the save.

I really want to know which mods are the roots of this error.

I really want to know which mods are the roots of this error.

Use Notepad+ if you aren't already, makes it easier to see the formatting for where the first <li> and closing </li> are. And of course, backup the save first.

Here's an example of what to delete. If I get the error again, I'll replace it with the actual section, but it should look similar.

Under this part:
<lordManager>
<lords>

There'll be a bunch of sections that look like below. Basically, each section is some event like a raid, visitors, trade caravan, etc. Just delete the whole section with the bugged lordJob class in it(ie.'LordJob_TradeWithColony') and reload the save.

<li> <faction>Faction_93</faction> <extraForbiddenThings /> <ownedPawns> <li>Thing_AM_Daggersnout92352</li> </ownedPawns> <ownedBuildings /> <ownedCorpses /> <lordJob Class="LordJob_AssaultColony"> <assaulterFaction>Faction_93</assaulterFaction> <canKidnap>False</canKidnap> <canTimeoutOrFlee>False</canTimeoutOrFlee> <canSteal>False</canSteal> </lordJob> <ticksInToil>7811125</ticksInToil> <numPawnsEverGained>1</numPawnsEverGained> <initialColonyHealthTotal>400</initialColonyHealthTotal> <questTags IsNull="True" /> <lordToilData> <keys> <li>1</li> </keys> <values> <li Class="LordToilData_ExitMap"> <locomotion>Jog</locomotion> <interruptCurrentJob>True</interruptCurrentJob> </li> </values> </lordToilData> <triggerData> <keys /> <values /> </triggerData> <curLordToilIdx>0</curLordToilIdx> </li>
