I realize it's frustrating to discover a bug such as the ones in the built in saving system, so let's all take a deep breath and calm down before anyone gets any angrier.
First, construct is in beta, which means all the bugs haven't been ironed out. No feature in the entire program should be considered to be 'advertised' as entirely bug free because of this.
Second, learning how to stay calm when encountering a bug such as this is an important and valuable lesson. Bugs exist even in professional development tools, so learning how to work around them when possible is also an important thing to learn how to do. In this case, using a custom saving system like newt suggested is the solution.
The devs are working to improve construct. However, construct is quite a complex application developed by volunteers in their spare time. Patience.
Irbis, it may be due to the langauage barrier, but comments like this:
[quote="irbis":148kss56]seriously instead of that biased Construct trailer, someone should make a list of messed up features in Construct.[/quote:148kss56]
...tend to be inflammatory. There isn't anything wrong with or biased about the trailer, it shows what can be done with construct in its current form, bugs and all. That said, a 'beta users guide' might not be a bad idea.
