Hey there,
With 2.4 we modified a few terrain assets near the new Siptah landmasses. The extent of these modifications is more limited and less drastic than the ones previously introduced with 2.3, however not informing about them during the Testlive period was an oversight.
For those of you affected on official servers, we of course won’t treat any partial buildings or assets that got stuck under the terrain at those locations as an infraction. But unfortunately, we also can’t help with any lost assets as Conan Exiles doesn’t offer MMO-like support on official servers.
We apologize for the frustration caused and thank you for bringing this up to our attention. We’ll try to better assess other possible changes brought to the Isle of Siptah map during Early Access and better communicate them in the future. We hope that the rest of the new content does at least improve your Isle of Siptah experience.
