After searching for a solution to my issue and not finding anything on it, figured it was time to make a report.

I created a function in the file location: "Kingdom/Minecraft/world/data/functions/test/brown_cow.mcfunction"

The contents are as follows:

say How
say Now
say Brown
say Cow

I reloaded the game and ran it successfully using the "/function test:brown_cow" command.

I tried creating a serious function after testing the above one successfully under the following path:
"Kingdom/Minecraft/world/data/functions/tracker/time.mcfunction"

The contents are as follows:

scoreboard players add @a[score_ticks_min=1200] Minutes 1

scoreboard players remove @a[score_ticks_min=1200] ticks 1200

scoreboard players add @a[score_Minutes_min=60] Hours 1

scoreboard players remove @a[score_Minutes_min=60] Minutes 60

scoreboard players add @a[score_Hours_min=24] Days 1

scoreboard players remove @a[score_Hours_min=24] Hours 24

scoreboard players add @a[score_Days_min=30] Months 1

scoreboard players remove @a[score_Days_min=30] Days 30

scoreboard players add @a[score_Months_min=12] Years 1

scoreboard players remove @a[score_Months_min=12] Months 12

I reloaded the game and tried running it using the "/function tracker:time" command.
All I get when trying to run this new function is "Unknown function 'tracker:time'"

I created both functions using the same methodology. One worked, the other did not. Why is this?
