| Dino Island Hot Fix #5 | 2022-06-24 | Fixed crash (introduced in last update) when moving a pen and dragging outside of the playable area. Recopied over old Morailty points to new system, that were reset inadvertently in the last update (This was related to the fixes for Euthanize / donate animals & Report Black Market & Critical Choice Scores). Note if you had done any work on these three morality stats over the last few days then this will have no effect on your game (we only reset values, where the newly created variable had a value of zero) Fixed an issue where changing the shape of an empty pen would result in the top layer of the world no longer rendering. (it was fun becau |
| Dino Island Fix #4 | 2022-06-22 | Fixed a bug where editing a pen with water inside could leave some collision behind. Changed the delete tool so it will delete deco inside pens, as well as outside. Fixed a bug where using the delete tool on water items inside pens would remove the collision from the water. Adding water to a pen wasn't instantly reflecting the multiplier it was applying to the enrichment (it would only be applied at the start of the next day). This has now been fixed. Using the delete shortcut action on items on water, would also delete the collision for the water (allowing people to walk on water!). This has been fixed. Garbage trucks were not coming on the |
