last valheim update breaks "Start"

[meigrafd]

Last Valheim Update 0.217.22 (n-15) breaks the "Start" button

[MonolithTMA]

Same.

[Battousai124]

Yepp, tested with many other mods that work. It does break.

[dcgsteve]

Just confirming - disabled all other mods and yes, can't start :(

Hope it's not too difficult to fix and you have time - good luck all!

Same here. Maybe some logfiles are helpful to debug the cause.

[wangmauler]

Same issue here. Found a few other mods we use that break the game in the exact same way too, if that helps at all. Any of these mods together or separately prevent the start button from working in game, and also make the characters not show up initially (have to switch characters).

@wangmauler, Harpoon Extended has already been recompiled and uploaded, proof: I contacted the author, and tested the new version so they could upload it.

[Geksli]

confirm this problem

[erikaxe]

I have the same problem as reported above.
