There seems to be something weird going on with the Boomkin Lunar Eclipse buff. I am running simc-330-5-win32.
Occasionally my output will show a Wrath/Starfire balance that is way off. Rather than Wrath/Starfire each contributing equally around 40% of my overall damage, Wrath will be at 20% and Starfire at 60%. When this happens, if I look at the Dynamic Buffs table I'll usually see Lunar Eclipse with an impossibly high uptime around 70-75%. Here is a simc file which displays this behavior:

Is it possible there's an unintended interaction going on between the Lunar Eclipse buff from the Eclipse talent and the Lunar Eclipse buff from the new T10 Idol of the Lunar Eclipse? The two buffs currently have the same name.
I've found two possible workarounds. I can replace the T10 idol with the old T9 Idol of Lunar Fury, or I can switch my actions list from Wrath first to Starfire first by replacing the last four actions on lines 23-26 with the following:
actions+=/starfire,if=trigger_solar
actions+=/wrath,if=buff.solar_eclipse.react&(buff.solar_eclipse.remains>cast_time)
actions+=/starfire,if=buff.lunar_eclipse.react&(buff.lunar_eclipse.remains>cast_time)
actions+=/wrath
Either workaround appears at first glance to fix the issue. The Wrath/Starfire numbers fall back into expected balance, so I'm not sure this is a huge issue or even an issue at all. But if there is an unintended mixing of the two buffs I'm not sure if I should trust either set of numbers regardless of whether Wrath/Starfire appear back in balance.
