Hi there! The server has been rather stable today, so we are officially launching the Technical Alpha period. The server will stay online as long as possible, and this version (3.2) fixes most bugs you've found and reported. We are still worried that the mobs might stop spawning at any point and we are trying to fix it, so if you see that the maps become devoid of mobs, please let us know.
(By the way, if you are not using the itch.io launcher you'll have to download the new client version here. Otherwise, wait until the launcher updates your client or force it to update by right clicking Eterspire and then selecting "check for update").
