Ever encountered errors like "!!!!VS PHYS THREAD CRASH!!!!" or "Too many frames in queue, is game stage broken?" in single-player or multiplayer? These often cause game laggy, making it nearly impossible to place blocks or shipfy blocks.
No worries! VS Safe and Sound is here to fix it. This mod catches potential crashes within the physics thread, including invalid forces/torques, unexpected constraint updates, and more.
The mod has been tested on several Forge servers and a single-player Forge modpack—everything works smoothly. While a Fabric version exists, it hasn't been field-tested yet. Any feedback is welcomed!
Additionally, sometimes removing VS addons prevents world loading. This mod can also handle it. It skips leftover addon data during save loading.
