Do you have dayz_code/configVariables.sqf in MPmissions/yourmission? Whatever you run?
If you do then you need to change this to what I post.
DZE_StaticConstructionCount = 1; // Number of animations required for building an object. Leaving set at zero will default to the construction count in the configs for each object.
You are missing alot of details here for anyone to help you.
I hope you are making backups of all files before you are doing any modding like this.
That is going to be your issue down below but without seeing the actual file you edited no one can point you in the right direction and correct it.
