This hotfix is currently only for Steam Windows 64 bit users but we thought it was crucial enough to get a fix out for our biggest user base as fast as possible. The fix for Windows 32 bit, Mac and other storefronts will roll out over the next few days.

Apologies for the confusing back-and-forth with this one - we released this update last night, but due to a change to aphids for a future update there was the unexpected effect of stripping aphids completely from the 4.x levels, so we had to revert it. All should now be well.

Patch Notes

• Fixed fire ants not being able to place pheromone markers on the surface in some freeplay maps
