With Blizzard changing the way enchant tooltips are presented I have noted that max.resists is not correctly parsing the new tooltip.
eg:
["Tooltip"] = "Circlet of Prophecy<br>Soulbound<br>Head Cloth<br>94 Armor<br>+17 Stamina<br>+27 Intellect<br>+20 Spirit<br>+10 Fire Resistance<br>|cffffffff+20 Fire Resistance|r<br><br>Durability 59 / 60<br>Classes: Priest<br>Requires Level 60<br>Equip: Increases damage and healing done by magical spells and effects by up to 12.<br> <br><br>Vestments of Prophecy (6/8)<br> Boots of Prophecy<br> Circlet of Prophecy<br> Girdle of Prophecy<br> Gloves of Prophecy<br> Pants of Prophecy<br> Mantle of Prophecy<br> Robes of Prophecy<br> Vambraces of Prophecy<br> <br><br>Set: -0.1 sec to the casting time of your Flash Heal spell.<br>Set: Improves your spell critical strike rating by 28.<br>(8) Set: Increases your chance of a critical hit with Prayer of Healing by 25%.",
note the |cffffffff+20 Fire Resistance|r<br>
In patch 1.12.2 the tooltip was captured as
["Tooltip"] = "Circlet of Prophecy<br>Soulbound<br>Head Cloth<br>83 Armor<br>+17 Stamina<br>+27 Intellect<br>+20 Spirit<br>+10 Fire Resistance<br>+20 Fire Resistance<br>Durability 60 / 60<br>Classes: Priest<br>Requires Level 60<br>Equip: Increases damage and healing done by magical spells and effects by up to 12.<br> <br><br>Vestments of Prophecy (5/8)<br> Boots of Prophecy<br> Circlet of Prophecy<br> Girdle of Prophecy<br> Gloves of Prophecy<br> Pants of Prophecy<br> Mantle of Prophecy<br> Robes of Prophecy<br> Vambraces of Prophecy<br> <br><br>Set: -0.1 sec to the casting time of your Flash Heal spell.<br>Set: Improves your chance to get a critical strike with Holy spells by 2%.<br>(8) Set: Increases your chance of a critical hit with Prayer of Healing by 25%.",
note that this time its a plain +20 Fire Resistance<br>
I suspect this needs a change to the 4 lines starting CONVERT approx lines 372-375 in maxres.php
