Rollback migrations on the server using ASP.NET MVC and Entity Framework Code first?

Question

ASP.NET

There is a remote server, a project is deployed on it on asp.net mvc 4.5 with a ms sql server database.
The project is connected to the database through the Entity Framework using code first and automatic migrations.
The essence of the problem:
If the project is not touched for a long time, then for some reason the migration rolls back to some incomprehensible, intermediate state.
Has anyone experienced this and how can I fix it?
And on my local computer, the project did not notice such behavior.
