There was an update to Arcane Mapper today - however to avoid confusion, I would like to clarify what is in the build. This version does not include the major changes that have been in progress since the last build, which is still on track as discussed in the last post.
Unfortunately some art assets were included in the previous version that should not have been. This build was released to rectify that issue, though there are a few minor fixes in as well. This will only affect people who purchased Arcane Mapper in the last few weeks, since the previous release. So if you are wondering why certain assets are included when they obviously shouldn't be - the issue has been resolved and won't happen again.
Note that Steam will not overwrite your Library directory, so current owners won't see any change to their Library. However new purchasers will not receive the extra assets that should not be included.
The next feature release build with the previously discussed lighting and performance improvements is still in progress and on track.
I hope this clears up any confusion.
