### Description of the bug

A hivelord, and most likely drone, can start a construction in front of itself to intercept RPG rockets.

In the video above, plasma is not consumed by the hivelord, indicating that the door was never actually completed. The rocket also visually travelled past the door and onto the hivelords tile, but the center of the detonation was the door itself.

### What's the difference with what should have happened?

The rocket shouldn't be able to intercept such a construction, it is ludicrous.

### How do we reproduce this bug?

1. Have RPG Spec prepare rocket
2. Have hivelord/possibly drone begin building
3. Fire past the construction

### Issue Bingo

- [] Issue could be reproduced at least once - (I will be testing with more projectiles and constructions soon, as well as with drone and queen eye buildings)
- [X] Issue happened in a recent (less than 7 days ago)
- [X] Couldn't find an existing issue about this (https://github.com/cmss13-devs/cmss13/issues)
