ERROR[EmergeThread0]: MOBF: failed to swap old conf file to new one

i saw this in debug txt when i play with animalspack 2.5.0
and there is no animal i the world

I've searched in the code and I haven't found what is precisely this error message. I haven't tested the new version of animals modpack yet.

There is a file called debug.txt in MT's files in which you can find the error logs. That must help us understanding the problem. If the file is too big, remove it and launch Minetest again with animal_modpack. So you will find a new debug.txt with only the informations we need.

Or you can try other mobs mods like Mobs Redo, that is much lighter.

Gael de Sailly thanks for attention. Like you said i download the Mobs Redo, when i try to run this mod i saw this error lines in debug.txt

Can you help me about that

You need to change the folder name to 'mobs' (remove -'master') for all mods you install.

We need to improve the mods system. That's a very recurrent mistake.

I still wondering why the -master is doubled in the file system after unpacking the .zip.

It worked thank you so much bro

I know that this is a very old thread, but I just have to say that these have been my thoughts for years on this subject. Whose idea was it to have everyone name their zips and the folder in the zip differently than the folder should be named when it ends up in the mods folder? Whatever problem this idea was trying to solve probably caused far less pain, over-all, than this approach has caused so many people over the years. Does someone consider this the best practice? If so, why? Hopefully, we can figure out where this came from and can stop encouraging mod developers to do it.
