Previously I could just use generic names like "drink" or "mortal strike" to track a wide range of buffs/debuffs. Now must I really go through every ability and extract all possible spell IDs to retain the same function?

Just as an example, I used to have a square dedicated to showing raid members who were under healing reduction effects.

Previously, I could simply have the square track the following:
veil of shadow;mortal strike;mortal wound;mortal cleave;gehennas' curse;23230

now that same functionality looks like this:
22687;28440;23224;7068;24674;17820;16856;9347;19643;17547;21557;13737;24573;21553;15708;21555;27580;12294;21558;21552;21551;25646;28467;19716;22859;23230

is this intentional and I just need to suck it up? It seems odd to take a "step back" here, where my squares are now much more difficult to configure and have lost all semblance of human readability.

These number based squares aren't even working for me anymore. How am I supposed to interface with this now? Is there a limit to the number of unique spell ids I can track in one square?

It's not working now even with limited spell IDs. A square I am using to track this single IDs doesn't work: 28440

This new "spell IDs" condition is very annoying. Made me come back to older version.

Fixed in 4.040
