Hey there Im totally new to speedrunning. Is there any autosplitter for borderlands 3? If not can someone help me to create one? I would aprecciate for any response.

There should be one if you set your game to Borderlands 3 on Livesplit.

I understood, but there is after the activation an error message:
Unexpected game version: OAK-PATCHDIESEL1-137 on egs.
Its for me quite hard to understand how to fix it

The issue is that the load time remover isnt updated for the new version so you either have to patch down to an earlier version or play without it and retime it after your run.

After reinstall everything, Ive got some other patch name issues . I think im gonna patch down. What do you mean with ''...or play without it and retime it after your run.'' ?

I think he must mean that you will have to compare the Time you made with the in game time

Well after couple of days trying to get fix it and patch down the hole game and trying some other sources. It doesnt work for me. Im gonna timing manually by pressing keys. Its not really accurate, but im fine with it.
