Official MGT2e Bug Report Thread

No problem at all. I don't usually use the original Core Rulebook. This is not something I would not have thought of. I wonder if there's anything else I'm missing by not loading it.
Lets hope that the skill problem is caused by this as well.

The latest update works with just the Update 2022 Rulebook. Thanks for the fix.

If you add an NPC to the crew of the ship in the party sheet you can assign them rolls like "Gunner". If you then click the "Show" button to display the available options an error pops up in the console 4 times.

Interesting, I was not aware of this functionality. I am seeing this error - "[ERROR] Script execution error: [string "CoreRPG:common/scripts/number_linked.lua"]:73: createChild: Invalid argument 1" are you seeing the same? I get two errors when using a pre-generated npc and four when I use one I created myself.

I'll need to debug the code to see what its doing and if I can fix it.

* I updated the code, please wait for the hotfix to be deployed.

Hello. I found a bug.
If you set a combat skill (Gun Combat, Melee, etc.) in the 'Skills' tab with a characteristic (DEX, for example), and you set a weapon with the same characteristic in the Actions tab, the 'Skill' field in the 'Actions' tab gains the characteristic's DM. You need to do a full cycle of the characteristic for the bug to occur.
You can reset everything to normal by deselecting the characteristic in the 'Skills' tab and doing a full cycle in the 'Actions' tab.
I hope I'm being clear

I am not saying you did not find a bug.

But I think you would not set DEX in both the Skills tab and the Actions tab (or for any other skill & action combo). If you do that, then your DEX (or any other stat) bonus is counted twice.

I added melee (unarmed) and Electronic (Sensors) by drag and drop into a new PC.
The following error appeared in the Console: [3/15/2026 5:58:18 PM] [ERROR] Script execution error: [string "MGT2:campaign/scripts/npcs_main.lua"]:170: attempt to index global 'skills' (a nil value).
It was the same error for both.
Note: I only have Mongoose Traveller Core Rulebook Update 2022 loaded.

I have fixed the bug, it will be deployed during the normal update.

The skill "Jack-of-All-Trades" from Core rulebook 2022 does not work. The skill "Jack of All Trades" from older core rulebook does work as intended. Someone should do a pass comparing the skills in both rulebooks and make sure they all work the same.

I've updated the code to check for the variant name, this will address the immediate issue. As reported on Discord, I've removed the block preventing the deletion of the Jack of All Trades skill and fixed the matching when dropping Heavy Weapons (Portable) from the core rulebook update 2022.

I've pushed a hotfix, your code should be updated once its distributed, please let me know if you find other issues.

Hello,
The 'Electronics' item type is misconfigured. It expands with 'Electronic' (without the "s") whereas all objects are included in the 'Electronics' type (with the "s").
Normally this should be properly configured as 'Electronics'. This concerns the items from the Central Supply Catalog 2023 Update.
Thank you.
