Oswald Will not wake up. After he crashes the ship, he just lies there. I have done all things in the neighbouring areas, and gotten all ingredients. *HELP!*

You can talk to him. Explore all menu options until you finally gt the option to yell at him. He'll wake up then. I don't know if it is necessary, but I'd use a character with high charisma and talk skills and such.

Oswald should wakeup after a little while whether you yell at him or not. He wakes up while Im fighting the beetles sometimes.
If he didn't wake up so far there might be a trouble in the game variables. I would suggest that you reload from a previous save coz it might be that other switches dont get tripped and you have more problems later on, which apparently have no relation to Oswald.

Yelling at him via dialogue gets you extra XP so do try that anyways.

I think the variable is OSWALD_HAS_NO_PANTS and it should be set to 1. At least that's what I deducted from my last savegame before chapter 2 and the first savegame in that chapter.

thank u. I'll try the variable, since i waited ages

I had this problem in one of the IWDII games I played. I had to reset the variable.

For me he always wakes up when I leave his ship.

I've never heard of him taking that long to wake up. Usually you just yell at him for a while.
