There is not enough information here to guess at an answer for your question. The important thing is that you are charged with a felony and need a lawyer to represent you, get one right away. That lawyer could tell you why the court is not moving forward. If you cannot afford to hire a lawyer, ask the court to appoint one for you, this is too complex a situation to handle on your own.
This response does not create an attorney client relationship and is offered for informational purposes only. Only a lawyer fully versed on the facts and circumstances of your case can properly advise you on the case. I am licensed to practice in Minnesota, not every state. You should always consult with an attorney licensed in your area on how best to proceed.
It sounds to me like your bigger issue isn't the rescheduling, but whether you believe you committed burglary in the first place. 2nd degree burglary is a serious charge. If you don't have an attorney, you need to get one to help you sort through these charges. You may have some issues that would help you avoid a burglary conviction altogether.
The case has had some court appearances rescheduled? That is not remarkable. Sometimes court appearance dates get rescheduled due to scheduling conflicts with other cases for one of the attorneys or the judge. That seems a trivial matter compared to facing a potential felony Burglary conviction, and the lifelong consequeences that would bring, as well as the prison or county jail time. Really, a Q & A site like this can helpful for getting a person moving in the right direction; but the right direction is getting a criminal defense lawyer to get to work helping you understand and defend the case. This would include gathering as much information about the facts as possible, then analyzing the facts in light of applicable law to find weaknesses in the prosecution cases, and potential defenses.
There are many different reasons why a court date could be rescheduled. If you have an attorney, I suggest you ask him this question. If you do not have an attorney, then it may be in your best interest to retain an attorney.
T he wheels of government move slowly. Trust your attorney.
