I want to create a tilemap in which its tiles are generated in runtime and in which the tilemap itself is generated in runtime by a factory. The problem is that if I try to generate a tilemap with the factory, the tilemap collisions don’t work, but if I try to instantiate the tilemap in the collection without using the factory, the collisions work. Defold version: 1.2.145 OS: macOS 10.14.2 Link to a project to simulate this bug: [MEGA](https://mega.nz/#!yGR12aKC!BNsN_PJB89oqW7rxKMaSaZGaIOCHmKDOz1WGxSK2usc) There are two collection in this project that you can choose to run: factory.collection for testing the bug and instantiated.collection to demonstrate that the collisions work if the tilemap is not generated by a factory. ---

Yes, this does indeed look like a bug. I guess it is a combination of spawning the tilemap using a factory and then using set\_tile() to populate the tilemap with tiles that causes the collision shape to not update properly. @Johan_Beck-Noren, @sven, @jhonny.goransson, can you confirm?

No, no update. We plan our next sprint (two weeks of work) tomorrow (Monday). We will evaluate and prioritise this issue during our planning session. ---
