After adding heart of stone update, i get a pop up box for red engine that says its compiling scripts and then gets

Error [content0]game\behavior_tree\tasks\monsters\bttaskmaintainspeed.ws(10): Class 'CBTTaskMaintainSpeed' already defined.
Error [content0]game\behavior_tree\tasks\monsters\bttaskmaintainspeed.ws(74): Class 'CBTTaskMaintainSpeedDef' already defined.

Error [content0]game\behavior_tree\tasks\reactions\bttaskisman.ws(15): Class 'CBTCondIsManDef' already defined.

and will not allow the game to start. I have added a couple mods to show buff and oil mods on the ui, could they be causing this problem? Anyone else?

Yes,most MODs that were made before 1.10 and touched the scripts in any way don't work with the 1.10 patch.

Might want to check if the author updated the mod, or disable it for now.

Just delete the folder
<Witcher 3 Install Path>\content\content0\scripts\game\behavior_tree\ tasks

Have fun

Or delete/clear your mod directory and wait for updates as TapfererToaster posted.

I had this problem (in vanilla game with few mods). Solution from another forum (worked for me):

Navigate to this directory: <Witcher 3 Install Path>\content\content0\scripts\game\behavior_tree\ tasks

Then delete the folder named "hacks" (make a backup of it first somewhere). Now everything should compile fine.

EDIT: By the way, this particular issue is not (strictly) a mod problem. It's a problem with the game's default, uncooked script files directory (at <Witcher 3 Install Path>\content\content0\scripts). It only crops up when script mods are enabled because that's the only time the game attempts to compile from that directory (instead of using the pre-compiled objects that the game ships with).

Removed mods and everything works fine now, thanks for the help though folks!

This worked great for me, and let me keep all my mods. Much appreciated!

Thanks this worked for me!
