I followed the steps to fix the bug, but my game keeps crashing when I try doing that. My world is 2.72 GB.

It does look just like it! These areas also had underground rain like mentioned in the other post and I did open the world in most snapshots, so I probably did on 20w17a.

Fixed in 20w13a!

@o62 I tried placing a block next to it after changing it to repeat, but it still didn't work.

Here's an extract of MC-156789, it's a duplicate post, but it has a lot of information about the problem:

Here is a list of commands in repeating command blocks that does not work:

(Boosts) If you are in a certain team and crouch and that your boost score is 0, you get an effect:

Command#.1 (Repeat): /effect give @a[team=Speedster,scores={Crouch=1..,Boost=0}] minecraft:speed 8 13 true

Command#.2 (Chained): /scoreboard players set @a[team=Speedster,scores={Crouch=1..,Boost=0}] Crouch 0

Commands that says when the boosts are on or off (the "Boost" scoreboard is affected by eating rotten flesh): (these 4 commands run in a loop)

Command #.1 (Repeat) /tellraw @a[scores={Boost=3}] {"text":"Boosts ON!","color":"dark_green"}

Command#.2 (Chained): /scoreboard players set @a[scores={Boost=3}] Boost 0

Command #.1 (Repeat): tellraw @a[scores={Boost=1}] {"text":"Boosts OFF!","color":"dark_red"}

Command #.2 (Chained): scoreboard players set @a[scores={Boost=1}] Boost 2

Here is a list of commands in repeating command blocks that does work:

If you walk on light blue concrete, you get a speed boost:

(Repeat): /execute at @a if block ~ ~-1 ~ minecraft:light_blue_concrete run effect give @p[distance=..3] minecraft:speed 1 15

Mobs have special effects:

(Repeat): /execute at @e[type=creeper] run effect give @e[distance=0..1,type=creeper] minecraft:blindness 10 0 true

From what I could see right now, the only commands on repeat that does not seem to work are the one that needs a specific criteria/another scoreboard objective to be activated (for exemple, having {boost=0} or {crouch=1..}).

Also, the bug is still happening in Snapshot 19w35a

It seems to be the same problem, I've also found another post which seems to be the same problem:

https://bugs.mojang.com/browse/MC-151813

From what I've seen, my post seems to have the most information about this problem, the problematic commands (and the ones that do work) that I've sent on my post would probably be a good place to start to try to fix this bug!

The backslashes in the commands written in that text (after scores=...) are not there in the commands on the map. I can't remove them from the description for some reasons.
