Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Beta Bug report Beta v1.0.80 collection thread.

I made a Wayfarer and removed Summon Spider, and then replaced it with Slow Current. Then I changed my mind and removed Poison Dart and replaced it with Summon Spider. When I started the game, I had two copies of Summon Spider and Slow Current on my skill bar. (It was still the same skill, the cooldowns on both activated at the same time.)
