WowAce

What version of Grid2  are you using (Version is displayed in General/About Tab) ?

 v3.0.11

What game client version, classic or retail, windows or mac and language are you using ?

 retail, mac, english client

What steps will reproduce the problem?

Using the alpha indicator with either range or range alt and target a friendly npc that might not be targeted by friendly spells. Mainly about target frames.

  
Did you try having Grid2 as the only enabled addon and everything else disabled?

yes!

Was it working in a previous version? If yes, which was the last good one?

Don't know.

Do you have an error log of what happened? If you don't see any errors, make sure that error reporting is enabled (`/console scriptErrors 1`) or install [BugSack](https://mods.curse.com/addons/wow/BugSack).

No lua errors.

Please provide any additional information below.

 Maybe a solution would be to add a slider to the range statuses that sets a range when range can not be calculated, so like a fallback alpha.

Not easy to fix, if  the target is not in range is because the friendly npc cannot be healed, so the heal range check is not failing.

And i think for healers is more important to know if the npc or player can be healed or not, so i cannot assume the npc is in range.
