Time Lords spawning crashes the game

[Hugobsb]

Specifications

Game version: Minecraft 1.19.2; Mod version: [Fabric] - Regeneration - 1.19.2 - v41.0.4; Fabric API version: [1.19.2] Fabric API 0.69.0+1.19.2.

OBS: Not working on the previous version too, [Fabric] - Regeneration - 1.19.2 - v41.0.3.

Explanation

The issue is happening because the game cannot find the skin file of the Time Lords.

Happening both in single-player and Aternos servers.

Manual fix

Mainly, I could "fix" this crash by pasting the regen_data folder in the root folder of the game, which I had to generate by opening the game with the Forge mod on 1.16, which is not working on the 1.19 versions of Fabric and Forge.

It's worth mentioning that this manual fix cannot be done on Aternos because it doesn't allow modifications to the root folder.

Technical details

As mentioned above, the Fabric version is not generating the regen_data folder properly.

Java error: java.nio.file.NoSuchFileException: ./regen_data/skins/slim

It is happening in the chooseRandomSkin method from the SkinRetriever class.

Unfortunately, I don't have permissions to add the proper labels for the issue, but I'm available to provide further details, if necessary.

[Jeryn99]

Do you know if a Forge server creates the folder?

Do you know if a Forge server creates the folder?

Unfortunately, it's crashing in the forge version too. I will update the Manual Fix section to make it clearer that I used a 1.16 version to generate the regen_data.

Do you know if a Forge server creates the folder?

I've updated my previous comment. So, no. It's happening on both Forge and Fabric 1.19 versions.

[Jeryn99]

I cannot seem to replicate this, potential aternos issue?

[Hugobsb]

I cannot seem to replicate this, potential aternos issue?

I don't think so. The same is happening to me when I install the mod and open a single-player world. I'm installing it through CurseForge

[KooBaby]

Im having the same- if not extremely similar issue on the 1.19.2 forge version on a multiplpayer server. If your manual fix doesnt work for me tomorrow when i try it i guess i'll post a new issue

[KooBaby]

i'm currently playing the regeneration mod in 1.16.5 to generate the regen_data folder. for some reason the folder wont generate for me to try your manual fix. does anyone know why this is? or could anyone potentially provide a 1.16.5 version of the regen_data folder
