Dragon32's solution appears to have fixed the issue for me.

You can try deleting my modshadercache, since it is only there because modbuddy hates me and i can't compile without it

Try renaming and copying over another mod's *_ModShaderCache.upk

Try and find a 371 byte one. Back in the early days there was bug where these cache files would balloon needlessly, I'd copy a blank one from another mod over a problematic one and things would still work OK.

I might fiddle with putting it somewhere else in the load order, using the config files, and see if that alleviates the issue for me. I'm running over 1600 mods, with my own config fixes/edits (ie: typos, incomplete lines, redundancies, and personalized balancing) for over 200 of them...so I expect to hit a snag now and then.

Is this actually necessary? I just checked my logs, and that file is the only shader cache file that prints an error. Opening it in a text editor also shows it as plain text (";A configuration File"), whereas other SDK-generated shader cache files are proper packages.

That file is just a dummy file that is there so the game loads the other upk packages.

I do get the same error, but I do am able to load the game just fine.

I'll take a look, thanks for the report

Receiving this warning in the log, there is no crash, but loading does not proceed beyond this point.

Oh, It currently does not work.I didn't even make it into the update. That, Heart Attack and Deadly Malabaris are currently not working. I pushed this update just so I could release myTrainee spec.

bruh, my mistake, what I really mean was hidden storm, the mine that cost 3 mana. Tried to use it but didnt appear on my custom class.

Storm Cut Mine is not a skill, it's just called Storm Cut. or Hare_StormCut for the internal name. I'll soon update with a .txt file with all the skills using their internal name

its storm cut mine not available?

@Harehnoth

Thanks for the fix. It works and I can keep playing and hopefully finish my campaign. Also glad I can keep using the Marathonist class in the future, which I like a lot.

thanks to everyone that helped as well

Fix uploaded

Mitz helped me with this issue, it seems there is an conflict with Extended Explosive Tweeks, I'll upload a fix in a few minutes @insectbrain

I'll take a look.

Strange, I can open ym game just fine, and all that I did was create more skills, nothing should have broke during startup.

@XpanD

Ok, just tried and the game wouldn't boot up.

If I had access to the older version of this mod, I would try to compare to see what's changed, or better yet I would just use the older version that doesn't give me problems, but I'm at the mercy of steam auto-updating mods.

thanks for your help

I wouldn't recommend saving with the LW2 Abilities mod disabled, but just seeing if the game starts up without it (but WITH Harehnoth's pack) might help narrow down what's happening here. It should boot, you'd just see a bunch of missing perks in-game.

@XpanD

I haven't tried, but that mod is a dependency for the amalgamation mod, amongst more in my mod list. The amalgamation mod is also a dependency for the marathonist mod, which is dependent on this mod.

I have tried only loading the marathonist mod with it's dependencies (along with their depencies) and got the game to start, so I'm assuming (I'm not a modder) the conflict has to do with my mod list and the changes introduced with this mod's updates. I have 571 mods, which I admit could make trouble shooting a PITA.

As stated before, I was able to load the game before the 3 recent updates to this mod and play just fine.

If I wasn't almost at the final mission in my current campaign, I would just delete the marathonist mod and start over, but I would like to continue if possible, but I don't think I'm able to fix this myself.

Not much there, other than that LW2 Abilities line. If you disable that mod but keep this one enabled, does anything change?

@XpanD

I hadn't checked CPU usage. Just did and it eventually, after a few minutes went to 0%.

Looked at Launch.log, The last section mentions Long War 2 Abilities for WotC.

Any interesting log output? If it goes to 0% CPU usage chances are there will be a crash report in the log, might have useful info.

The recent updates have (i'm assuming) caused a conflict for me. I can't even get to the startup screen as the game stays in an unresponsive state upon launching from the AML. Worked fine before these updates.

I can however get the game to start by disabling this mod and the one mod that is dependant on yours.

This is the other mod that has yours as a dependency: https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=3032722870

I was hoping there is an easy fix so I can keep playing my campaign that uses your mod.

It adds skills for my specs. Curretnyl it adds Flash Fire to my marathonist spec. I'm tinkering with skills for my future specs atm.

what does it add tho

Great mod, I have a quick question, is it compatible with Civ 7?

Congrats on the release dude
