The GOG Version was updated by Larian once again so a few bugs were fixed but there´s still plenty left.
Im not sure about the Tingalf quest but in general it isnt a good idea to do the quests in a weird order (happens if you play the first time often) or to carry items with the skill "Magic Barrier" ever because it might lower your resistances to unbelievable levels (e.g. -106783) so you instantly die after one attack.
It´s also a bad idea to carry items that gives you +1 on a skill you already maxed out to lvl. 5 because it causes weird bugs too. (e.g. Aura of Command makes you control an endless amount of resurrected or summoned monsters instead of just five)


But all of this won´t be a major problem as long as you save every half hour or just read through the Help/Tips/Tricks & Technical Problems forum.

For the list of bug fixes you probably have to send an email to the support forum of GOG or wait for some of the oldies in the forum to help you out.
