Thanks for opening this thread. That was also my idea. To explain what happend yesterday.
And what is possible to fix this.

Every single server in DayZ can load 2140 classes.
What is a class? A class defined the item. Every item in DayZ has a class. The items wouldnt work without class define.

I pushed my update yesterday with much new items, this mean much new classes.

Serverowners with much Mods near the limit 2140 classes got an error message. Some deleted mods step by step. And suddenly it works.
They send me a message with the conflicting mods. I got more than 10 messages with different conflicting mods.
But there is no conflict itself with that mod. The issue is the class limit from 2140.

Because this, my update was working for some people and for some not.

What is the solution?

Bohemia knows that issue. And they reported in his update notes, it will be fixed in 1.10.
Im not sure because that. I hope they do.

The easier way is to reduce the mods on your server. Make sure you really need all mods. Make sure you need multiple Weapon mods, car mods, clothing mods.......

What's my plan for future? I will upload my update after the 1.10 update.
The issue is fixed - cool
The issue isn't fixed - it's on you to give more space for classes

Can't do much more.

Thanks for the explanation, and it's now clear why I could load your mod once I got rid of FIDOV. We'll happily wait for 1.10.

I have to say thank you to you. Thanks to help me and respect my work. Every single dollar is very helpful for me to get new great models.
1.10 update is coming. I hope there is nothing to repair for me after this update. It's nothing to fix in my mod, I'll push my mod update at the same day.
