Hello,
Found a serious bug in Haste and Slow component of the SpellpackB6. This component adds effect with opcode 221 - Remove spell type protections. This effect is added to spells and items with Haste or Slow effect. But problem is following: this effect is set up incorrectly. Effect with opcode 221 uses Secondary type (Spell type in NI) code to remove specific protection. But in SpellpackB6 this type is set to 0. Instead in 221 opcode effect name of the resource is given. Problem is that resource is ignored in opcode 221 effect. So we have secondary type that removes all effects, including equipping item effects! Moreover this bug is spread to a lot of items. For example, Mustard Jellly slowing attack item, Strange antidote potion etc. Strange, but those sympthoms are in effect only with Slow. Haste spell doesn't remove any protections or afflictions. (However, didn't test haste with negative effects)
Suggested solution: set correct secondary type for 221 opcode, because resourve names are ignored.
