Crash - Registry Object not present

[Blugori]

Hi, I ran into an issue while creating a modpack when I tried adding this mod.

Minecraft version : 1.16.1
Forge : 32.0.108
Flamingo : 1.0.1

Minecraft crashed and said :

The game crashed whilst initializing game
Error: java.lang.NullPointerException: Registry Object not present: flamingo_ooo:flamingo_spawn_egg
Exit Code: -1

Crash log :
crash-2020-09-20_22.42.29-client.txt

This particular crash tends to be caused by other mods failing to load before our one. We've come across it a bunch, as it turns out - could you upload your latest.log from when this happened?

[Blugori]

wow I didnt expect an answer that fast xD I just encountered the same issue with your gentle fawn mod, can I give you the latest log for gentle fawn instead ? or would it be messy

[gdude2002]

Either is just fine!

[Blugori]

latest.log

here it is !

[Blugori]

I just added 20 mods at once so it might be hard to find the problem, I can try to put them one after an other

This appears to be an issue within a mod called Mapper Base. Feel free to drop them a message - here's the relevant stack trace.

For people running across this issue in future: Registry Object not present errors are often caused by mods failing to load earlier on in the mod loading process. Before reporting this problem as an issue, please take a moment to read over your logs (starting from the top) and look for other errors.

Unfortunately, Forge is well known for eating useful errors when it comes to crash logs. It's just the way things are.
