Under development

It can. Wipes usually happen when major systems change, the world is replaced, or an early economy gets distorted by exploits. If you are attached to long-term builds, assume anything is temporary until the server explicitly commits to permanence.

Yes if you enjoy being early and can handle instability. Time spent can be devalued by balance changes, world edits, or resets, so the payoff is more about experimenting and shaping the direction than securing permanent advantages.

More variance than usual. Performance tuning often involves profiling, restarts, plugin swaps, and hotfixes, so you may see spikes of lag, temporary disabled features, and short maintenance windows.

Give reproduction steps: what you did, where (coordinates if possible), what you expected, and what happened instead. Include your Minecraft version and any client mods or resource packs that could affect behavior. Use the server's preferred channel rather than spamming staff in chat.

Conduct rules are usually stable, but mechanical edge cases can be handled case-by-case while systems are being hardened. Some servers want exploit reports without abuse; others treat exploitation as griefing. If you found a loophole, ask before pushing it.
