Market
Mythic items can now be sold. Mythics you get from battle drops or Arena milestones can now be listed on the Steam Market, including ones you've found since Hotfix 3. Mythics from forging, wave boss rewards, and items that got upgraded when they dropped stay account-bound. Selling limits are unchanged. You need to update to this build for your Mythic drops to be sellable. Mythics found since Hotfix 3 qualify once you update; older ones stay account-bound.
Equipment
Steam items stay equipped. Items from your Steam inventory (for example, ones bought on the Market) no longer pop out of their slot when you restart the game. If this happened to you before, just equip the item again once — it'll stay put from now on.
Forge
Fixed an issue where clicking Forge multiple times quickly could cause problems.
If a forge doesn't go through, nothing is forged: materials that weren't used up come back to your inventory. If some are missing, email [email protected] with the date of the forge.
