During the ambush of the Vanishing Bandits in Roth Roryn, I got an error message saying "Scale parameters for Magic Effect Drain Attribute are bad" followed twice by "Scale parameters for Magic Effect Drain Skill are bad". Then I was forced into [inventory] menu mode, and I could not exit it, so the game was essentially frozen. It turned out that the reason for not being able to exit the menu is that the corresponding script disables player control, so I was able to proceed by enabling it back through the console. I have no idea however what is causing the player to enter menu mode, but if this cannot be resolved, the disabling of player controls has to be removed.

After reenabling controls I got the force greeting anyway, so the disabling may not be necessary, but I guess it might be possible to escape before that otherwise, so this should be checked. The error messages are certainly due to the spell that is cast on the player, TR_m4_RR_TeleportBanditTrap, which if working as intended definitely should prevent the player from getting anywhere anyway unless using a spell.

I am including the coordinates of the encounter.
