I dont know if it is meant to be like this, but the main stairs leading from the spawn appears to be badly damaged.

Yes, some people do tend to ruin the spawn area from time to time <object class="emojione" data="https://resources.enjin.com/1489581540/themes/core/images/emojione/svg/2639.svg?0" type="image/svg+xml" standby=":(">:(</object>

I'm not sure whether it's classed as grief or not, but the best thing you can do is repair it <object class="emojione" data="https://resources.enjin.com/1489581540/themes/core/images/emojione/svg/1f642.svg?0" type="image/svg+xml" standby=":)">:)</object>

is it ok to repair it then? I wont be had up for interfering, griefing or anything else will I?

No no, as long as you don't destroy something that looks nice already <object class="emojione" data="https://resources.enjin.com/1489581540/themes/core/images/emojione/svg/1f642.svg?0" type="image/svg+xml" standby=":)">:)</object>

Repairing places from holes (that you think shouldn't be) there is a good thing <object class="emojione" data="https://resources.enjin.com/1489581540/themes/core/images/emojione/svg/1f642.svg?0" type="image/svg+xml" standby=":)">:)</object>
