[STEAM][0.90.11][Objects disappear] Thrown spears on constructions disappear

It is not specific to a version, but was always like that. When I throw a spear on a construction, lets say a raft or a foundation It just disappear after saving and reloading.

I thought it was minor bug and didn’t report it, but now it seems the devs just don’t know that.

Arrows of any kind just went through any building, just like it wouldn’t exist. What would be another bug in my view.

Seed
any

Settings

Steps

  1. throw a spear on a raft or foundation.
  2. Save the game state.
  3. Load the game state.
  4. the spear disappeared.

This does not happen when it is simply dropped or is through on the real ground.
