While playing, I encountered a crash that appears to be known as seen by this thread:
http://forums.larian.com/ubbthreads.php?ubb=showflat&Number=500447Through debugging the game, I've discovered this isn't due to being encumbered but rather being marked 'Too Heavy' which tries to block movement altogether. For some reason, this messages' floating text causes the game to crash when popped up in the manner its setup for. The crash, in the current Steam version (v1.506) is happening here:

To fix this, we can patch the exe to prevent the first jump from happening.
Please note! I have not played long with this patch in place! So I cannot say for sure this will fix the crash and not affect anything else during gameplay! Please backup your saved games and your exe before making any changes that I explain below!!!What You Need - Beyond Divinity (Only tested with the Steam version. 1.506)
- A hex editor. (Any that can scan for byte patterns will work fine. I use 010 Editor personally.)
How To Patch This Code1. Open your hex editor.
2. Open div.exe inside of the hex editor.
3. Go to the following file offset: 0x17D956
4. Change the
74 2F at this location to:
90 905. Save your div.exe and close the hex editor.
For other versions, you can attempt this patch as well by searching for the following byte pattern instead of using the direct file offset:
2B D1 C1 FA 02 F6 47 04 01 74 2F
While using this pattern instead, change the last two bytes of the pattern from 74 2F to 90 90 like above.
This should fix the crash for this 'Too Heavy' floating message now and allow you to play as normal.
You will be blocked from moving while 'Too Heavy' vs. just being slowed down while 'Encumbered'.
Was there every any SDK or debug symbols (.pdb) released for the game? Seems a lot of the resources for the Divinity titles have disappeared over the years. 
Just finished the game too.
