Looking at the log, this does not seem like an MSU-related issue. I'd say try asking about it in the Legends Discord server, maybe it is related to that mod.
- MSU requires Modern Hooks which you are missing. - If you still have error after that, then try removing your mods one by one until the error goes away. It is possible that some of your mods are not yet updated for new vanilla version i.e. 1.5.1.
After updating the MSU1.7.0 (from 01.April.2025) the game (vanilla) cannot be started at all (it worked OK with previous MSU 1.6.0. The error is: "Mod mod_msu failed to set function onMovementFinished in bb class scripts/skills/skill_container: there is no function to set in the class or any of its ancestors during its hook on bb class scripts/skills/skill_container."
This is not related to MSU. Check the compatibility of your other mods. You can also join the [BB Modding discord](https://discord.gg/eSsNqrerfk) and share your game log to help us identify your issue.
Hi there. I've tried all the modding discords available and no one has helped me, so maybe I'm luckier here. My game has come to a point where I get a crash every hour with a critical exception. I've removed mods one by one until only MSU mods and the two script hooks mods remain. But I still get the crash.
The weird thing is that I've logged 800 hours with most of those mods without many issues. Many years ago I suffered the same crash but messing with the audio and control in the game optinons checkboxes solved it. Also the crashes weren't nearly as often. Here's my log in case someone can help. The only "new" mods I've included since these happened are the MSU launcher and the Turn Order numbers, both of them MSU related, so I don't think they're the cause.
The weird folder at the beginning called "Mods in barbecho" is the folder where I keep the mods I'm not using. I don't think that's the cause either.
This is the whole ordeal and specifics with different logs and the evolution over the years in case it's needed: https://www.reddit.com/r/BattleBrothers/comments/1i1vupa/anyone_can_help_me_with_my_log_and_critical/
The only different thing I've noticed with these crashes it's
1. No action is required. I just left the computer on during the battle and when I came back it was frozen. 2. This is new: when the crash occurs, it loads a screenshot of a previous battle (!!!). Never seen that before. Also, crasher are ALWAYS exclusively while doing battle.
I have genuinely no idea, the one thing I'd recommend is that you remove the mods in barbecho folder because stuff in there can get loaded in a strange if I remember correctly and that may well be causing your issue. If that doesn't fix it, I'm not sure.
I get an error when I try to start the game I have modern hooks installed and this is my log -- bblog66.tiiny.site the error says "Mod mod_msu (Modding Standards & Utilities (MSU)) version 1.6.0 had an error (the index 'm' does not exist) during its hook on bb class scripts/items/weapons/weapon."
Thanks for posting your log @SnarfMcSnarf, one thing I will say is that you have a LOT of mods, especially if this is your first time. This seems like a mod conflict to me, so if you could try and track down what combination of mods is causing your issue we would be able to take a look, with such a big modlist, it could be a lot of things.
Hey there. Recently added this in as per the instructions on steam but now when I do that the game crashes telling me that the MSU mod failed to set function onMovement Start in bb class scripts/entity/tactical/actor and that there is no function set in the class or any of its ancestors.
Then I get a bunch of src: Scripts/Entity/Tactical/ect the index does not exist. I am a complete tech illiterate. Can anyone help me with this?

Your mods are awesome! Your work and effort is deeply appreciated.

Only figured this out because I was going to upload the log files but it ended up working surprisingly.
