This is how software development works and dota is a complex game with complex logics and interactions, so probably many hacks due to a lot of changes (patches bla bla) so if they don't have unit tests (at least) to perform verifications on the code base, it must be a hell of a job to fix bugs in the game without breaking something else (aka introducing new bugs). :]
This is a programmers joke:
```
99 little bugs in code
1 little bug fixed
100 little bugs in the code
```
