structure entrances

there are underground structures that have not any proper generation or at least a proper entrances, some are just facing the whole solid wall similar how trial chamber generates they don't have a proper entrance they're just placed somewhere deep underground without any cave that leads to it, what is so disappointing is that you to mine your way in instead of finding the entrance, for me what i love the most is to preserve the structure because i like how this built, i hope mojang fixes their structure generation :)
