Just to let everyone here know a problem I've been having since the update.
Normally after an update to keep mods working I go into the wurm launcher folder and run the patcher. I downloaded the latest one from the forums today. After running patcher and modlauncher wurm will not run at all. Steam says it's running for a just a few seconds then disappears. Restarting steam did not fix. I verified the files through steam and it said one file was needing a download and then afterwards the problem was fixed only no mods in game. I repeated the process to get mods working. Ran the patcher etc. identical problem happened. I had to verify files again through steam and it downloads a file about 16mb long same as before. Again now the game works but no mods in game.
In case anyone wants to know, I was finally able to fix this problem by deleting the mods folder entirely and redownloading every single mod. Then running patcher and modloader. So for now problem is fixed.
I installed the client-modlauncher-0.8 and all the other 0.8 modules of the mod loader and it fixed my issue where the client wouldn't start after running the patcher.bat file. If anyone has the same issue.
