I have been using several macros for this expansion They have performed well. After your latest update I have all kinds of compile issues. The macros are priority type and relatively short (I know what does short mean ). No more then 8 lines mostly castsequence.
no special calls to other macros. They are calling out compile errors for length -350-1800
I like the block concept but am afraid to change or test just yet

Each block works as an individual element. A WOW Macro can have a total of 255 actions (command blocks) before it breaks. If you have a Priority loop with 5 lines in it and repeat that 20 times your macro is when compiled for execution 1050 actions long plus anything outside of the loop. This is past the 255 limit. Prior to this and as noted in #901 WoW would just spew out a bunch of errors and your macro would not work.

If your macro is just priority and 8 lines long - set the repeat to 1 and the warnings will go away.

Sorry did not mention I am not using the loop function on any of them nor am I using pre or post macro. The macros worked fine in pre 3.0 . Would shortening and chaining the sequence solve it

Can you give me an example? It's kinda hard to see what's in your macro or what it compiles to without something to work from.

hey @woodgray

Is this still an issue for you?

Going to close this out for now - yell if i need to look at this again
