Report Bugs, Issues and Suggestions Here!

Welcome to Icarus' Bugs and Suggestions Board!

Please make sure to be CLEAR and CONCISE when providing your feedback on bugs and issues. Feel free to add photos, or links to videos or drives for more information. We will be using google translate to edit any suggestions not in English.

Before you write a new suggestion, try searching a few keywords, and you might find another suggestion that matches yours. We will only be considering suggestions that have a high number of upvotes, and will not be looking at low voted or low detail tickets. Messages on our social medias or discord will not be officially considered. However, our discord contains many experienced prospectors that would be happy to try assist you with an issue before posting here to help us out.

We will try to reflect the status of each ticket as soon as we can.

We cannot promise all bugs will be fixed asap, but we will prioritize which are most pressing, so search for your issue before you post!
If there is a critical bug or issue, we will let you know on our Twitter @SurviveIcarus if we need to make a fix while you are playing.
