I run into Multiple issues with the steam trainer 1.0.0.2.
When i start playing for example i notice that through the game certain things will just gradually stop working until it becomes unplayable.
First with adding levels it just stops the ability to add skill points, and if you add too much experience it can interfere with many quests. Like i'll speak to someone and then i can't walk.
Or when i bring up the menu nothing will be there, or i wont be able to click anything, I've ensured that this is the right trainer.
Running the trainer as admin has just sprung to mind, so i'm going to go ahead and give that a try, and maybe running the game as admin as well, (I should have tried that in the first place) I'll let you know if that doesn't work. But at the moment i've had to reset my character about 5 times now D:
no idea if adding XP too high or adding levels too high too early in the game breaks scripted or managed events.
i've played MY character for hours with max skills/abilities.
i find there is no need to use XP any more since you can add skills/abilities at will using the trainer. the level up buttons are so you can buy the skills/abilities that require later levels. you can buy them and then level back down to where you were.
if you had the wrong trainer NOTHING would work and likely the game would crash.
pressing the keys when you shouldn't or improperly (see the instructions) can screw up your game as well.
best,
Cal
