Old code isn't the issue, the real problem is too much being added too fast

A lot of people here are mixing up "old code" with "inveitable bugs", and those aren't the same thing. Yes, COC is an old game, but that does not automatically mean every update has to break core systems. Old, well-maintained codebases can be extremently stable. Bugs usually come from process issues: rushed releases, weak regression testing, not age alone.

Just because Clash is f2p doesn't mean it gets a free pass. Players who invest money or time deserve a stable, reliable experience. In paid software, repeatedly breaking core existing functionality isn't acceptable. Users don't care why it broke, only that it did. "Bugs happen, get over it" isn't a technical defense. At the same time, a full rewrite or just put more resources is unrealistic. What does work is incremental refactoring, cleanup, and slowing adding features.
