Plantuml diagrams get mixed up or only placeholder is shown

[staffann]

Lately a problem has started to occur when plantuml diagrams are embedded into markdown files. The problem is frequent but not entirely repeatable.

1. The plantuml diagram is not shown. Instead a placeholder is shown. Any change to the diagram causes the diagram to be shown. When reverting the change, the placeholder is shown again.
2. A different plantuml diagram is shown than the one defined in the particular location in the markdown file.

When we generate pdf files from the markdown files using pandoc all diagrams are generated and shown correctly.

This is a major problem for us since our main usecase is to use this plugin to previous markdown files with plantuml diagrams.

We are experiencing the same thing, unfortunately I am always getting the "Welcome to PlantUML" placeholder. Did you happen to find a solution yet?
